HA HA Belinda, your mum sounds like mine!
I have been dropping hints left right and centre and she's like 'that's nice dear' and then keeps talking about whatever, like will I finish uni this year and will I be working at Christmas, and then it's my turn to be vague since my husband told me not to be too obvious
Come announcement time, I know one mum who will be flabbergasted! It's just too funny...
