too many reasons why we cry :) For example :

This is stupid Example sooooooo, don't do this at home >.< or anywhere you go :)

                                   if you friend doesn't text you back in 2.22 seconds

                                             When your mother calls you

                                              When your shower its too cold

               when you forgot something that was in the next room and you have to stand up

                                when the truning lights turns red before you could go
