Sorry for whinging so near Christmas 
Came back this morning, in fairly hazardous conditions, from working last night to find dp & the children playing in the front garden. dp went inside & shut the door but told ds he could stand by the front door while I parked. Trouble is, our drive goes up then down so have to rev a bit then glide down, can be a bit hairy at the best of times. All it needed was for practical joker ds to step forward to shock me (which he could easily decide to do - still thinks he's immortal) & horrible things could have happened. In the end I parked on the road instead because ds couldn't understand why I was contradicting his dad.
Anyway, long post for a simple question - was I being over-cautious or was dp being a bit thoughtless? He's much more relaxed than me - when ds was tiny dp would regularly leave stanley knife blades on the floor from diy jobs & get cross with me for 'nagging' so we've definitely got different attitudes. (Not that I'm trying to sway your opinion to agreeing with me
, oh no, not at all.)
