I never have anything to talk about.

[Shattering -]

I Have the same 'problem'. It seems that all my friends has some interesting things to talk about, except me.
That's why I always talk nonsense. My friends know this. When we have nothing to say, I start talking about unicorns and the difference between pancakes and waffles.

I Wished I had something serious to talk about with my friends . I Read A LOT (Just fiction books), so I can talk about that (I Guess?), but most of my friends don't read, so they don't talk about that =P.

Don't force yourself to talk crap that you don't like. Just talk about crap that you like. If you like smurfs, tell your friends, they will give their opinion and off you go.
