I do most of my short runs in some woods where there are a few runners and a lot of dog walkers. The dog walkers are mostly very sweet but my utter fave is the woman who always says "gosh you're SO fast!".
I am really very very slow, but bless her.
On my first ever 10k race when I was nearly dead there were a bunch of kids (maybe aged 8-12) outside their house, SCREAMING at us as we went past, things like "you are all so cool!" "Even walking is winning!" "Your mum is proud of you!" "You are such a superstar!" "Keep going, you look GREAT!".
Ever since then every time I have run a race which is suggested to have "great crowd support" I have been disappointed. Nothing has ever matched up to that.
