1. I was getting tired of going to bars and being the oldest guy there. To me, it made me look like I had a drinking problem.
2. Working afternoons, I got tired of being followed home by the police... especially when I hadn't had anything to drink and was just going home from work.
I may have one or two drinks a week now and I guarantee you I won't get behind the wheel when I do imbibe.
I figure I was lucky for a long time to not get pulled over and I didn't want to press my luck.
