Have a seat anywhere........

I was coming home from Houston on Wednesday night.
So very thankful that I got my First Class upgrade... That way I don't have to sit and chant "they are touching me..... they are touching me....ewwwhhhh".
I get on the plane, I am in the third row. I was probably about the tenth or so person to get on. I am getting situated and have a window seat. The Flight Attendant comes by to see if anyone would like something to drink while we finish boarding. My standard is Baileys or Kahlua, helps with the nap I plan on taking for the next four hours....
This young kid sits down next to me, very polite - asked if I would like the isle or am I happy with the window seat. I tell him, that it doesn't really matter to me, if he would prefer the window - I would switch with him. He seems all good - and orders an orange juice.
About five mins into the boarding process, an India (that would be with the dot) in a business suit stops at the isle. Looks at his boarding pass, and says to this kid - are you in 3D?
The kid, gets out of the seat, doesn't look for his boarding pass or question the other guy, and walks straight for the back of the plane.
I kinda give the guy across the isle a funny look - as he does me. Was like "wow glad I didn't switch seats with him, or I would be in the wrong seat". The flight attendant is watching all of this, and comes back over and says to the business man. "Would you like something to drink, or would you like that guys orange juice?"
I guess you never know - if you don't try?????
