i was in the passanger seat. i looked towards her to make my point and she pulled out a semi-miniature blottle of Listerine - a really cute round one NOT the rectangle kind... guzzeling the bright blue stuff with one gulp while she's turning onto Lake Shore Drive... THIS IS WHAT YOU GET WHEN YOUR SISTER STUDIES DENTISTRY.I proceded to try to make her laugh ~ of course so I could see her squirt toxic mint out her nose. She giggled but no luck. so... yah... my personal trainer/wellness person is cool. She's a bit flighty.... but cool....
