Me Time | A Mother’s Limerick

Reading in bed, what delight!
Yet this “me” time is never quite right
For as soon as I lay
I’m so pooped from the day
It’s as if someone snuffed out the light.

The grammar stickler in me worries that the use of “lay” is improper; I’ve left it, however, because of the rhyme. Where are my fellow mamas – hands up, and high five!
