Its dh's 40th birthday today. This evening we (the children and dh and I) are going out with his parents, my 2 sisters and their dhs. We've all arranged to meet at the restaurant until MIL called dh yesterday saying they dont know where the restaurant is despite the fact its on a very busy main road. They've said they want to travel with dh, me and the children in our car. We've recently bought a new 7 seater but on the proviso that we dont use it above a 5 seater, dh is pissed that I keep ending up with everyones kids because we can fit them in. So dh apparently has said to his mum (after explaining that she does know where it is and the road hasnt moved in all the years she's lived in Brum) that they follow us. They wont do this because his "dad doesnt like driving". They have to drive back to Evesham tonight after the restaurant though and would be just as easy to travel to/from directly. I know they expect our children to go in the boot but we dont allow them to. Help me to piss my MIL off
