Bumblebee on the slide

This afternoon, I was putting the slide together.
I had to pick up something, on my return I found an exhausted big bumblebee on the slide.
The neighbor also took a look at it and said, “maybe he needs some sugar water? " This I offered the bumblebee, however, he did not want. I saw something I haven't seen before. He stabbed his paw up. It was like he said, “ho, I don't have to."
A little later he became more active and raised a paw to the neighbor.
What funny all this looks like.
Eventually, the bumblebee flew away again.
