Today my sister started the day saying she won't talk in the whole day except when she has to talk on the phone specially with her boyfriend and if she has to communicates with people she would only use signs.
Her reason to do this is - as she says- she has been complaining a lot about everything and she's been mad at everything so she decided to behavior like this so she wouldn't get any feedback that would annoy her. She likes to criticize most of the things she does or uses, but that's the way she is. Maybe it's true she has been complaining a lot but she doesn't have to reach that limit.
In my opinion, I would say that it has been one of the worse decisions she had made because not talking it's a bad position to be in, not just because it is extremely boring but because you just get to understand the things that you are doing wrong but you don't get any feedback about it and that's very important to change.
And after all a day without her talking is like reading a book with no plot or listening to a song without melody, or looking a painting without colors.( I think you've got the idea)
After all I hope that she realizes about this soon so everything could get back to normal
To my sister: Don't forget that I will always love you after all.
