If I never knew before...
My sister and I can really be polar opposites sometimes. New reason: I passed my road test on my first try, drove for over 3 years before I got my first speeding ticket. Sis? Passed on her third try, has barely had her license for 3 months, just got her first speeding ticket. My theory - even though we can both have lead feet, I try to stay in the confines of "over the limit, but not far enough over that the cop will want to make the effort" (well, except for the one ticket I got - 73 in a 55), whereas she hasn't quite mastered that concept yet. 78 in a 55! Yikes!
