So I ran into an old friend who's now a lawyer and graduated from the law school here. I said to her "it's great to see you, how long are you in town" and gave her a hug. She turned out to be a girl from my class. With make up on, she's a dead ringer for my friend. She's very reserved and proper. I have never felt so awkward in my whole life. I explained that I thought she was someone else. That probably just added to the awkwardness.
You're thinking of the wrong blue... although bluepervert probably works equally well for both
awkward follows you like a beer chasing a shot of tequila.
I am very proud to say that the other day I thought I saw my friend walking in front of me in the direction we walk to the bus and I was going to shout out to her and didn't. Later she turned around and wasn't my friend at all. I've learned from my awkward ways.
