31. Biggest pet peeve? Having to remind a lot of online friends that I am a lot older than they are and may know the odd thing.

Nodding like a mad thing, over here. It's infuriating, isn't it? Not least in my case because it reminds me that I was just that level of "of course I know every damned thing in the universe and have experienced Life, with an upper-case L of course! I'm nearly twenty-two, damn it!" myself, back in the day.
