AIBU? Neighthours and dropped kerb

[Mummysboy2014]

Right so we own a bourse with a dropped kerb directly outside our house. Next door do not have a dropped kerb they have a big tree at the end of their driveway assuming they can't get permission for a dropped kerb. Anyway so we have 2 cars next door has one. They use our dropped kerb to access their driveway as they wouldn't be able to access it otherwise. Last night my partners car was parked on our drive, I parked on our dropped kerb and was taking the shopping in. Next door pulled up behind me beeping their horn. I continued to get the things out the car took them to my front door, he beeped the horn again and I shouted wait. I then got the baby aged 5 months out the car and came To the front door to which my partner had now opened the door to see what was going on. I walked back to my car and got my toddler as he didn't want to get out the car. Next door beeped the horn again. Aibu in thinking his an arse and you know what he should be grateful as, Correct me if I'm wrong I'm allowed to park on my dropped kerb. And if it weren't for us he wouldn't be to access his drive without using our dropped kerb.

I really can't see how anyone with a driveway has never ever parked across it for some reason for a few minutes; driving back to get something you forgot, dropping someone off, carrying something large out that you couldn't get over the driveway if car was in it.

It happens frequently in our road and everyone seems to get on even if they happened to be obstructed by a neighbours car for a few seconds

Battleaxe thank you .....I have mi moments The way I figure it (looking at the pics we have) is that the NDN either has to go off at an angle on the pavement to go across to his driveway (which is illegal surely if we all started driving along pavements even for a few feet to avoid an obstruction etc ) thus avoiding having to go on OPs property.....or ....if he drives in a straight line over the dropped kerb he will end up obviously on the OPs drive and then have to veer to the left to go across to his. So he is either driving over someone's property or driving along a pavement not accessed by a dropped kerb to make it permissible.. Where's the OP btw ? So many questions I''m becoming obsessed and NEED to know the answers
