Owlie, it's great your mom is actually willing to buy you items for your cycling attire and "addictive habit". I think it's just cool!
I'm in my early 40's and my mom still frets when I'm on the road. She's paranoid about being clipped to the bike, "what happens if you have to react fast? how are you going to respond?" I used to tell her when I did century events, she would stay home by the phone in case anyone called her about me, so out of guilt I stopped telling her when i would do charity rides. I always told her after the ride was over.
