A quick kiss. Holding hands. I like to see couples show affection for each other in public. Nothing that would embarrass anyone of course. Just holding hands I think is very sweet. Maybe William and Kate do that too but Harry is very enthusiastic about it! I guess reticence for showing emotion in public isn't limited to Brits.But I do think Americans in general are more demonstrative. I expect watever you're used to is best, right? Different strokes.
