Why does alcohol = awkward?

Random encounters/conversations from this week. Both are from one night at the Rocket Bar in DC.

First, I get up to the bar and someone shouts" ****'s Office" ( I'm not going to mention the member of congress I work for) and I look up. It's some guy who looks vaguely familiar,  he then says "I'm from ******'s office!"  He then proceeds after a few moments to come over and talk to me and my friend.  He says that he recognized me from passing by my office everyday and seeing me at the front desk, his office is down the hall.  We exchange names and he says he'll look me up in the universal email address book at work, great :-/ Thankfully, as of today I have not seen him or been emailed so lets hope that he just got drunk and forgot.

Second Enounter...same bar, same night, a random guy comes up to me and my friend and starts to make conversation with us.  It was just your average drunken convo, where you from, having fun, etc...until this guy asks about ROOFIES! He just dropped it into the conversation casually like "so do you guys ever do roofies together? You know do roofies with your friends?" WTF! Who talks about that! WHO???!!!  It was so creepy! I immediately made sure my drink was no where near this guys hands and I looked for Joe who thankfully was approaching, so after listening to a few more roofie related questions I ran to Joe's arms and my friend grabbed another guy who is friends with Joe and I and part of our group and pretended he was her bf.  So yeah....a conversation about Roofies....not exactly normal just really creepy.

So to sum up, awkward guy from my office and a conversation about roofies. Let's hope this is not a part of some creepy pattern.
