Believe it or else... er, believe it or not, some believe they have to be with a partner, on a date, to have fun.
Someone was talking to (well, complaining at) me one day about how she was single, couldn't find a guy, life is no fun, she can't go anywhere and do anything because she doesn't have anyone to go with. I asked why couldn't she go to a movie by herself? She said "It just isn't the same."
Frankly I couldn't understand that, and still can't. I can have fun alone, with a group, with one person... fun is fun!
