When I was about 16, I had a problem with sharing I tended to 'over-react' when someone asked me to share. One day in the park I had a whole share bag of malteasers to myself and a small boy asked me for one. Instead of just saying "No" I decided to scream "WELL HAVE THEM ALL THEN" and throw the bag at the poor kids face.
Now I realised that kind of behaviour (I'd do it to everyone) wasn't acceptable and wanted to be able to offer people things but still found it difficult when people said yes. Luckily I found a loophole in the system and I'm going to share it with you now.
I refined my palate to like things that not many people like E.G : Iron Bru, Liqourice and peppermint tea, rainbow drops and liqourice and blackcurrant sweets. Funnily enough now when I offer people these things I don't mind if they say yes..
