Single people have problems too, and is so hard sometimes cause u don't have someone at home when u arrive so angry to calm down, u must call a friend or familiar... They dont understand u have your own problems, think that their problems are more importants than ours.
I love one of the episodes of Sex and the City, when Carrie is stolen at friend's home (her Manolos!!! has dissapeared). Finally she remember to her married friend that she isnt married and dont have childs, so she paid so much money as presents for her married friends and that's privilege that single people don't have.
