Not sure how it came to this, but I got into a dispute about a ball. Possibly losing my grip on reality...
At soft play loads of coloured balls are brought out. DD (20 m) usually selects one and plays with it throughout the class. Today she rolled the chosen ball down a slide and it rolled to the feet of a pre-walker. He was crawling by his DM who was chatting to a friend. He put his hands out towards it but my DD picked it up and ran off with it. I rolled another ball towards him.
The next thing his mother dashed over and roughly snatched the ball from my DD saying "My DS was playing with that. Dont steal from babies". Cue my DD looking really surprised and then bursting into floods of tears.
I picked up sobbing DD, explained that DD had been playing with the ball and demanded it back. The mother then dropped the ball on the floor and walked off saying "well take it then if it means so bloody much to you. You'd think there are enough bloody balls here". DD got the ball and carried on playing. However as we were leaving the mother whispered loudly to her friend: "such a brat, so bloody spoilt. You'd think they'd teach her to share".
I carried on walking but was fuming. However when I told my DH, he found it hilarious that I got into an argument over a ball. Am now thinking perhaps he's right and am 
. What do you think, WIBU?
