I agree on the profanity part, but come on, his profile says he's 10 years old, you adults could have posted less sarcastic or negatively to his off topic threads. (this is small talk after all). So he likes busses, so what? You don't have to knock that.
10 year olds might not understand sarcasm sometimes, and if marmite is discussed in lenghts then why can't he have his non-SS threads without silly or sarcastic remarks. If you have no opinion about a thread topic, then why post negatively and make a young forum member feel bad? What if I would say I hate marmite, in every topic it comes up in.
Oh and btw... I hate marmite, it is made from the devil's dingleberries and it stinks... there!
