super awkward situation - what would you do, OOT?

[DING-DONG YO]

I was at a wedding this weekend and my friend walks out of the bathroom. He said that while waiting to piss (1 stall), the little boy who was in the wedding was in front of him having trouble taking his pants down to pee. Finally the little boy asked my friend to help. My friend said he stepped back and looked around for the kid's Dad or something but no one was to be found.

He said he quickly undid the kid's belt so he could pee.

So, what would you have done? Let some poor kid piss himself or just lend a hand and risk getting caught in an awkward situation?

I'll lend my thoughts later.
