True! My kids are at that 'Ewww, gross' stage when my wife and I PDA in front of them, but when I ask if they'd prefer the alternative (i.e. us not wanting to PDA) they always say no.
The person below me has been hugged tightly by their kids recently.
Edit - I just realized that I used some of our 'college slang' that some may not know. We used PDA to mean 'public display of affection'.
