Or, "Let's eat Grandma." Commas save lives I tell you!
Reminds me of that song Everything Back But You by Avril Lavigne :)
"I wish you were her!" ... nice one I can just see worlds collapsing after the husband presses the enter key ...
"I'm going to watch my little sister, take a shower then eat." and "I'm going to watch my little sister take a shower then eat."
