My son's absolute inability to sleep past seven a.m., no matter how late I permit him to stay up, can FTFO. So can his inclinations to go looking for his sister, and wake her up for company.
I was awakened this morning by the wails of a strongly unhappy little girl who really wasn't ready to wake up. She's in the sleepy part of a growth spurt. I bet that, if she could, wasn't asleep again, and had the terminology (and if Mama wouldn't wash her mouth out with soap), she'd tell her brother to FTFO.
I sympathize. I wasn't ready to get up, either.
