The other thought is that gigglies and smoochies, etc. in restaurants even between a young guy and gal will get that same response from some kids (in fact it's even more likely to get comments of one sort or another from same kid :-)

yeah, Himself and I get gawked at every once in a while - we tend to be pretty affectionate with each other. I blame it on the fact that we lived 2700 miles apart for the first 6 months of our relationship. :)
