To Swap

In "Words with Friends" you have to know Exactly when to swap, For sometimes with the tiles you have You can't come out on top. The same is true in life, I guess; At times we have to trade Our car, our job or maybe spouse Before our chances fade. I mostly hold my letters, though, And rarely make a switch, Since upgrades are among those things For which I have no itch. I play with three opponents And of course I lose a lot, Perhaps because I mostly tend To stick with what I've got.
