my mother thinks im stupid!

on my mums 55th birthday she had a party and i wrote a 'this is your life' type skit with pictures which my oldest son read out, i made my mum bawl like a baby!

well i turned 30 a few weeks ago and im having a party in may, and now every time i speak to mum she asks me stupid questions 'how old were you when such and such happened' 'how did you feel when this or that happened'

do i look stoooopid? like im gonna fall for it! so ive given her all the wrong answers that'll teach her
