I agree, 10.15 is too late. Don't pubs usually have a cut off time of 9pm?
I think it's fair to expect some time to drink in adult only company later in the evening.
Besides which I always feel very restricted around children in that I have to watch what I say and only talk about 'nice' things within their earshot. It's a bit inhibiting. Maybe others think that's a good thing..but we all need to release a bit of tension and discuss the issue of the day with our adult friends, whatever that issue might happen to be - and we should be allowed to do that at 10.15pm.
