I've been away with work for a while with a colleague who's something of a friend, we're not particularly close but have worked together for about 4 years. I've really enjoyed her talking about her two children (I don't have or want children), it's fascinating and highly entertaining at times.
Someone mentioned a book they might enjoy when we were at dinner and I really wanted to get it for the two toddlers, it's only a few pounds. Would that be a weird thing to do?
