Yes i know i am, but its like.. one of those ingrained things i learned on my mothers knee 
Don't go out with wet hair when its cold!
It's like there is a constant shouting match going on in my head between Sensible Cherry and Old Wives Tale loving Grandma!
Every time DD (7) mentions she's got swimming class tomorrow, its like Old Grandma suddenly sits up and goes "she shouldn't be out with wet hair in this cold, she'll get sick, they shouldn't be taking the little kids outside in this cold straight from a hot swimming pool when they never dry themselves properly and are still damp with wet hair!" and then Sensible Cherry tells her to sit down and shut up, but she carries on grumbling ominously in the background.
Anyone else have those kind of inner wars with themselves? Or am i just nuts?
