it's like the eye of a duck

I've found I do the same thing with Krav and working out in general. It seems the majority of my friends come from KMDC now, which isn't necessarily a bad thing considering I'm there SO much. While it is important to keep in contact with older friends and to not subject them to talk of things they don't fully understand, its also important to remember that you ARE getting out of the house and doing something you love. Sharing that fact with everyone isn't a bad thing.
