Scrabble

I have too much Scrabble in my L I F E.
 
I play for words while others
play for points as soon as
they come in the door.
Constantly rearranging,
but never getting the answers
I'm looking for.
If "X" marks the spot
and "Y" asks the question,
where does that leave "Z"?
And if "U" "R" always right,
then where does that leave me?
I can't see the end,
though I know it's there.
And all I'm left with is a
single blank wooden square.
