Thank God your uncle showed up just in time, children can be very childish at times.
The same thing happened to me sometime last year, I was inside my cousin's car with my son and her daughter, we were leaving her house, so she stepped out to open her gate and by mistake, the car doors got jammed.
I tried opening it, but I couldn't, and immediately I started sweating, I was looking at my cousin as she was walking away towards the gate and she was making calls on her phone so calling her was out of it.
It wasn't a cool experience, at all. We remained there until about a few minutes before she came back tit o open for us.
Cheers to us for surving that, from a fellow #dreemerforlife
