I know I'm a very bad letter writer but ..........
I was thinking for you the other day

entered the priciest item on the menu

And you must know why this fact ..........
has fixed in my mind
has adhered in my mind

has stuck in my mind

I only had a ..........
a very modest plate
a very modest number
a very modest dish
a very modest bowl

This was just as well in view of what ..........
