And I wonder why I don't get flowers

Because no good deed goes unpunished. (Or unquestioned.)

The Spouse: [Walks into my office & presents me with a beautiful bouquet of roses and spring flowers.]

Me: Did someone send me flowers?

The Spouse: Me, I did.

Me: Aw, sweetheart, they're lovely! Thank you! [Gives the spouse a big hug and kiss. Then pauses.] Wait, what did you do?
 
The spouse: Nothing.
 
Me: [Eyes him suspiciously.] What are you not telling me?
 
The Spouse: [Now giggling nervously] Nothing! I love you and just wanted to surprise you with flowers.
 
Me: O-ka-ay... [Gives him another hug and kiss... and a side eye.] Thank you?!
 
The Spouse: You're welcome.

And I wonder why I don't get flowers more often (or at all).

(Actually, it's because our two cats eat them and knock over/smash the vases.)
