Congratulations on becoming a grandad very shortly. You will soon have every excuse, license and obligation to be grumpy, leave your slippers lying round in front of the fire, swear and mutter under your breath when spoken to, move your tongue round your mouth while eating so that everyone can see, and make all sorts of painful noises whenever you move any muscle in your body.
LMAO!
Congratulations to all the family, I think he/she will be a very lucky baby with all that love around him/her.
