I meet a lot of people that I would never meet in my ordinary work or social life at they gym. The people in my life are both true originals and at the same time quite homogenic. My youngest acquaintance is a guy at them gym and I ran into him the other day. I think his age or my perception of his age created this confusion.

Young guy: So, how are you doing? 
Me: Really well, went out last night but nothing fancy. Just coke. 

He suddenly looks at me as I was completely insane.

Me: Coke as in Coke. 

Not helping myself.

Me: As in Coca-Cola. 

Still looks at me with a weird face.

Young guy: You mean Zero? 

Me: Yes, that is what I mean. 

Young guy: Regular Coke is just a no go area.
