I've been searching everywhere to find out what movie a scene is from. It's a bit vague but maybe someone knows...

There's two people on a bench (a couple I think) and they are looking at and talking about an old couple and how happy they look.
Someone either is eating taffy or suggests getting some taffy.
They then go to get the little train thing home but one of them says they will walk.
Sorry for the vagueness!
