I won't even wear a hat in the rain, mostly because my hair's usually not long enough for the effects of rain on it to be apparent (as it's normally at skinhead length so it can't end up looking greasy and unkempt). I don't particularly mind rain much. When we go on about "Typical British weather" here we're usually kidding and just get on with what we're doing.

If one of my friends uses an umbrella, I'm almost embarrassed to be seen with them XD
