Groups of chavs standing somewhere that I'm gonna have to walk through with my girlfriend.
With you on that one. Never sure if something will happen. You could say that about almost any group of people standing around but it just seems more likely that chavs will start some thing for no reason.
Bees and Wasps. After being stung over 20 times in the head by Wasps, I have a not so irrational fear of them.
Had a similar experience when I was 10, now I just get laughed at when I try and dodge wasps screaming like a girl. THEY DON'T UNDERSTAND!
