The thing about aging is that it sneaks up on you -

Like today for example. I noticed when I walked into the barber shop that there were only old farts getting their haircut at 8:30 in the morning...

And then it hit me.
1) I was there
2) I had beat them by 15 minutes

and I realized this when I was coming back for the 2nd time - I'd already gotten my haircut - and hard forgotten my jacket.

fml :)
