I didn't write this but I ran across it many years ago and have always liked it.
Trust is a very strong word
A powerful meaning broken in two
This word is formed around one letter
And the letter is U
For U are the one I live for, the only one I love
And if U remain by my side, the U becomes an US
For US means no other love, only me and you
And from this day forward, I promise US
Forever I'll be TRU
TRU to our relationship, in hopes it never RUST
For you are the one I give my love,
The only one I TRUST.
