Do I drink a lot???

Here's a thought that I've been pondering all day. Do I present myself as a person who drinks a lot? Well this is how this whole thought process came about. Last night, I received a call around 12:30 AM from a friend. She was so drunk that it was hard to understand her because she was slurring, and she could not finish her sentences. She kept saying, "I'm so drunk, and I can't focus. What should I do?" I haven't talked to this girl in months, and why of all sudden did she call me when she was drunk? People who are not regular drinkers do call me to get advice on drinking. Does that mean I'm an "expert" in drinking? I can honestly say I do have a lot of experience, but I honestly don't feel that I drink a lot. Or maybe, I'm just in denial. The truth of the matter is, I'm a social drinker, and when I was in college, I was around that scene more than I wanted to. My one rule with myself is never drink alone, so that means I haven't picked up a drink in my house for 4 months. Since I've moved to Vegas, I found myself working overtime everyday, and cannot even go out to the bars. From an outside perspective, does it seem that I drink a lot???
