Daddy's Whiskers

As you were both still awake even though it was past your bedtime, daddy decided to play a little with the both of you. 
He rubbed his chin on Mei-mei's cheek and she giggled. You heard her laughing non - stop and peeked at what we were doing on the bed. Daddy asked if you wanted to know what he did to Evelyn.  You said yes. So he also tickled you with his whiskers when you closed your eyes.
When asked if you knew what it was, you replied "I know.... it's daddy's whiskers" ... then added "Daddy's got whiskers because he drinks whiskey".
Hahaha.... I wonder how you figured that out.
