Yeah 99% its the parents that reacted the same way in front of their kids. I think the same is said for other fears such as spiders, lighting, thunder and so on its down to what they see round them.
Either way. I try and keep away from public places and people at the best of times.

And cant fcking stand dogs running about parks knocking kids over licking there face, With some fat bird with a bum bags saying he'sjust sayin
