Postcard from Uganda: More local expressions

Since my last 'postcard' about language, I have begun to learn some words in Luganda and learnt some more local English expressions.

• "sorry" - used in the same way as Australian English (to apologise for something you've done), but also to express sympathy for something that clearly has nothing to do with you. For example, I was telling a Ugandan friend that we had discovered a decomposing rat in our apartment, and she said "Oh, sorry!". I have heard it many times since in similar kinds of situations - e.g. when telling someone I'd had food poisoning or had hurt myself getting into a bus. It sounds strange to my ears because in Australian English, in those kinds of situations people are more likely to say something like "Oh no, you poor thing!" or "Oh, that's terrible!" or "How awful!" You may hear "I'm sorry to hear that" in AE, but it's more likely to come in response to more serious bad news such as a death or chronic illness or relationship breakdown or loss of a job.
• "we pray from…" - instead of saying 'we go to such-and-such church', most of the people I've met say 'we pray from such-and-such church'. So now instead of asking "which church do you go to?" I try to remember to ask "where do you pray from?". I'm intrigued as to how this phrase came about, though, as Christians know we can pray anywhere and God will hear us. Maybe I'll find out one of these days.
• "benching" - this is a genuinely Kampalan term, and in fact it originated at Makerere University where we are living and working! Apparently it stems back to the days when there were just two residential halls, one for women and one for men. The one for women, Mary Stewart Hall, had some benches placed around the foyer and the young men used to go and sit there on the benches waiting for the object of their desire to come walking through so they could talk to them or take them out. They could sit there for hours, and so the expression 'He's benching' came about to describe this activity. Now the meaning of the term has apparently broadened. One meaning is when someone you know comes to your place and hangs around and it's hard to get rid of them - "they're benching". Another meaning is when someone is trying to get to know someone of the opposite sex and tries to spend as much time around them as possible - "he/she's benching". Apparently there are other Makerere terms that have become widely used, but I have yet to find out what they are.
• "where do you stay/sleep?" - if someone wants to find out where you live, they ask "where do you stay?" or "where do you sleep?". I've even had someone asking me "are you sleeping around?", which means "are you staying somewhere around here?", not the meaning Australian (and probably American and British) English speakers would understand from it! However, if someone says "he/she's sleeping around", it means they are away for a few days, e.g. out of town on business or visiting a friend or relative in another place. A Ugandan friend told us that this expression had caused a lot of concern to her British-English-speaking friend who was looking for her in Kampala and was told "oh, she's sleeping around" because she was out of town!
• what not to ask: as in many places, it's very rude to ask a woman's age. For men, the question of age is nowhere near as rude as asking how many cows he has (which would be like asking someone how much he earns or how much he has in assets).
