I don't think I do much in life very well. I'm middle row average on most things I pursue.
But there is at least one thing I excel in; I make an amazing sandwich!
It would be wrong to say I JUST make a sadwich. You wouldn't say DaVinci JUST painted and you wouldn't say Mozart JUST played the piano.
So please never suggest I JUST had a sandwich for dinner.
I had a masterpiece for dinner.
