I feel so bad about this. I was in the kitchen serving up dinner waiting for dh to get home, and all three of them were playing in the hall.
I heard what I thought was the front door shutting, but I only just heard it if you know what I mean, I was serving up and thinking about other things.
TG I investigated. I couldn't see the dt's and said to my three year old, "did you open the front door", as I said this I ran to the door and opened it, and saw them running down the drive.
At the same moment, my dh drove up to the bottom of the drive.
Thank god, he doesn't park in the drive, thank god he wasn't a couple of seconds later (they were nearly at the end of the open drive), thank god I heard the door.
All this is cruelly ironic, as I posted only a couple of hours ago on one of those threads about leaving your children alone, about how you can't watch them all the time in the house.
Ds1 has no clue what he did, he said " dts wanted to play in the rain".
