Oh, I forgot to mention that you might caution yourself when using dirivitives of the word which describes your interest in stamps. To uneducated people they think that word is the same as another which describes a sexual act.
You might get some response like, "Duh, I'm smart too. That just means that you like giving blowjobs, right?"
While that chacterization might hold, the intent of actual conversation is subtle mostly and speaking can be dangerous at times. Ignorant bastards, some are.
