Oh I hate this ..
Children shouldn't be forced to have adults touching them if they aren't comfortable with this

I don't think approaching would've been the best thing to do but those sorts of interactions drive me nuts.

Most old men I see are repressed perverts...I wouldn't let my kids around them alone.

Sounds like this weirdo may have a fetish for tickling children. Yuck.

Its incredibly common for adults to totally ignore, or even worse, condemn children for speaking up.

I've seen a father play fight with his son, meanwhile the son kept telling him to stop over and over. The mother butted in and asked the father to stop, and the dads scowling reply was " oh come off it , we were just having fun , he knows that "

But the only one smiling was the father.

And I wondered how many times he did this ...and never saw that he only upset and scared those that loved him.

Some people are just terrible, terrible, terrible parents.
