I think the following story really sums up last night to a T.
I was sitting at my desk this morning trying to figure out what was wrong with my work e-mail when my co-worker walked in. She had not been in yesterday so besides her bringing my morning coffee, I was excited to see her.
"How was last night? Did you go out?" she asked.
I looked at her like she was insane, I had no idea what she was talking about! Then she laughed and looked at me saying, "That good huh?!"
Oh My G! I had totally forgotten that I had gone out with "E" last night!
So, there it is. It's clearly not necessary to put in details about the date, since as of 10 AM I couldn't even remember I had gone out on one in the first place!
