I generally try and avoid asking him to "babysit" (his term) for me when I'm doing church stuff/going out.
But for church this evening I was a bit desparate - so, as he's pulled his socks up recently and has been having them every Saturday and Sunday (and recently started overnights again too) I decided to ask him.
Phoned him Thursday night
"yes I think that will be ok, can you text me on Saturday to double check"
So - I texted him yesterday
he replied
"yes that's fine,can you ring me 1/2hr before you need me to remind me"
WTF!!! He has a fancy modern phone which he puts reminders on - why on earth couldn't he manage to put a reminder on that if he really could't remember between Thursday pm and Sunday pm that he was looking after his own children for a short while this evening!!!
