does not mean phone at 7.45am (although that in itself is ok as to was to wish DS happy birthday) and say we'll be round about 1pm.
That's what MIL did this morning as it's DS's 6th b'day. I have things to do and haven't got time to entertain them for 2 hours before pick up at school. I might just go shopping this afternoon instead of this morning so that I'm not here.
