That's how I feel today. Took care of a heartsick friend last night. Took him out for "a couple of beers" which in Depressed Man Speak means "a couple of pitchers with nothing to eat beforehand." So yeah, I drank beer, but only to make him feel better. He had 2 pitchers, I had a few cans of beer, and we called it therapy.
He and his wife separated because she's immature and decided she doesn't want to deal with kids anymore (they have 1 together, he has 3 from a previous marriage.) So what's she do? Goes out, sleeps with a guy that he KNOWS, and gets knocked up. My friend has had a vasectomy, so he knows it's not his. Karma towards her, but poor guy....
So Terry came out around 10 (I was starting to get sleepy by then, with all the beer and having worked all day) and we sat there and were entertained by him until 1am, when our friend said "Hey, since you're driving me home, Denny's is on the way. Wanna stop for some food?"
Yes. I had the cheese fries with ranch dressing.
And the WORST part of this whole thing is.....I never used to be old, tired, and fat. It seems like just a year ago, I was sitting at Denny's until 4:30am, eating nothing but garbage after drinking way too much at the bars, and never gained a pound, never thought "I'm too old for this

," nothing! I used to party at the bars until 3am....now here I was sitting at Denny's at 1:30am, trying not to fall asleep because I have to follow Terry over to our friend's house so Terry has a way home.
Incidentally, our friend that we took care of is 11 years older than I am. He was ready to go dancing after Denny's! Ugghhhh. I said "You boys can do whatever you want, but I'm going home and going to sleep." (I get just a little *****y when I'm tired.)
Got home at 2am, went right to sleep, got up just before 10. Still quite groggy. I can't do this anymore.

The things we do for our friends.
