I don't mind question, I actually like when people ask questions as it's a good way of learning (given the answers aren't too stupid), but some questions gets asked almost daily, and you don't even have to search to find all the answers you need, just browse the front page of each suitable forums at least. I don't think it's too rude to point that out to people, in a nice tone, after answering their questions.

I'm 6'2" and had a high horse once. Even at my height it was difficult to get on, it just got really paranoid and would sleep all day and then at night go out and steal mobile phones to sell for drugs. Eventually everything got to much and I had to kick it out.
