Ok, so I know IABU and it was a spur of the moment childish thing to do but ........
Upon leaving the supermarket with a 1yo and 3yo in tow, I get to my car to find a man struggling to get out of his van because he has parked so close to my car.
I politely pointed out that if he is struggling then how am I expected to get my 3yo into his car seat when I cannot open my door.
His response was "it's not my problem"
Me : well it's now my problem because your an incompetent arse
Him: fuck off you stuck up btch, and walked off with his mate laughing
Whilst my 3yo was climbing over my 1yo to get to his car seat, I unloaded the shopping and came across the eggs.
I splatted one on his windscreen and bombed it
Very immature of me I know, but I think he deserved it!
