I am glad your mum liked her new bag and the lovely dinner you took her to. Sometimes it's nice just to have a chance to sit down and chat with mum's isn't it?
My mum and I were sat having coffee the other morning just chatting (it'd been ages since we'd done it) and we were having so much fun we forgot to keep an eye on the clock and she was late for work.
It's lucky her boss is so nice.
