You could at least have asked how he is!!
Even if you do not have the manners and curtesy anymore to hold a normal conversation other than on the net, (you brought me up alright so I am living proof that you did have them once), you could have asked how your grandson is, knowing he was in hospital 😦
Failing that, it would have been nice if you could have taken the message for my dad to at least let him know that my son is ok but no, like a silly child you put the phone down on me.
Well shame on you!! You don’t deserve to be called Mum or Gran any more 😦
