We don't get particularly 'bad' ones here. But last night we had the worst one in my memory. I have two rabbits and this thunderstorm just came out of nowhere. I had to run out and fetch them in, the poor things were shaking.

When I was younger I was scared of them, I think most children are. Now, I'm not so bad unless it's whilst I'm trying to sleep. I think you're more aware of them then.
As I was growing up I did used to like counting the distance between the flashes and crashes. I think it's a good way to get children relaxed during them.
