Download e-book for iPad: A Través de una Ventana (Spanish Edition) by Mayca Galiana

By Mayca Galiana

Este libro introduce al lector al mundo de l. a. virtualidad que ocurre en una sala de chat real.
Es una invitación a conocer de forma distinta lo que el ser humano refleja de forma diferente a lo que sucede en l. a. vida real.
Una mujer es quien refleja, a través de sus vivencias, y como en un espejo, los sentimientos humanos, que con frialdad y calidez, se trasmiten a través del lenguaje más antiguo del mundo: los angeles escritura.
Un lenguaje digital es el alma de este libro, una computadora y sus componentes, el cuerpo del delito o deleite.
Los relatos son vivencias exactas de gente que es, existe y vive, quizás junto a nosotros mismos y que ni siquiera podríamos imaginar.
Mi propuesta es que lo disfruten, que aprendan que no todo lo que decimos es lo que sentimos, ni todo lo que sentimos es lo que decimos.
Si por casualidad o por mi profesión de Psicóloga, en verdad, no lo sé, pero he leído y sabido de tantas historias de amor y desamor en mi Sala de Chat, durante los tres años que he sido participante activa.
Quizás sea este el mejor momento para sacar algo de ellas, aprendizaje, quizás. Todas están muy presentes e intactas en mi memoria, tal y como sucedieron, por lo que en mi humilde opinión,compartirlas, será un recíproco aprendizaje.
Empezaré diciendo que los angeles computadora es una de mis armas de trabajo diario y diversión. Me encanta estar buscando biografías de poetas, l. a. poesía es una de mis pasiones; estar enterada de política, de cine, en fin, de lo que pasa a mi alrededor.
Un día, por casualidad tropecé con un anuncio que decía: “CHAT”.La curiosidad y el ocio me llevaron a una página donde me pedían poner un Nick o apodo. Pensé en uno, lo puse y de pronto estaba dentro de una página con muchos títulos. Como period mi primera vez en un sitio de esa índole, he de decirles que recorrí todas las salas, sin que ninguna llamara mucho mi atención. los angeles única que más o menos ganó mi interés, fue una de música, en ella habían dos personas y ninguna escribía. Saludé y no obtuve ninguna respuesta, abandoné el sitio y no volví a entrar en mucho tiempo.
Otro día de aburrimiento, regresé al chat y me metí a una sala llamada: Chat Cristiano, sin ser yo muy creyente y siendo mi religión católica. En esa sala casi todo el mundo period de diferentes religiones, menos de l. a. mía, había testigos de Jehová, cristianos de diferentes nombres, sin embargo, ahí me quedé un buen rato. De pronto, una gran discusión empezó, habían entrado a l. a. sala, gente que sólo entra a molestar; lo primero que hicieron fue insultar y hablar mal de Dios. Yo como character nueva ahí, no dije nada, sólo leía, hasta que me aburrí y me salí.
La curiosidad, el morbo, no sé explicarlo, me hizo regresar al otro día, y fue así como poco a poco fui haciendo amistad con una character de l. a. sala, cuyo Nick y nombre cambiaré, pues hasta el día de hoy seguimos siendo amigas, le nombraré Gisela. Hubo veces que quise entrar a los angeles sala y no aparecía el nombre, es decir, no l. a. encontraba, así que un día le pregunté a Gisela por qué ésta no aparecía en algunas ocasiones. Ella me explicó que cada quien puede crear o abrir una sala, en cualquier momento y cuando uno lo deseara y me explicó cómo hacerlo y eso mismo hacía cuando los angeles encontraba cerrada. Nunca participé mucho, pues me divertía más leyendo que escribiendo, ya que es preciso decir que no me gustan mucho las discusiones sin sentido y eso period lo que mayormente ocurría en tal sala.
Sabiendo que se podía abrir una sala en el Chat, se me ocurrió abrir una con el nombre de “Poesías y Pensamientos”, ya que lo que más me gusta a mí es los angeles poesía y resuelta y decidida así lo hice.
