Russian bears take no chances. It's even on one of their flags:

Is the part where we say about how someone has fed that bear and that bear is going to kill some person some day?

I would not in any way shape or form be able to maintain that kind of composure if I ran up on a Russian man sitting on a bench like that.

That bear has nerves of iron.

I'd be pretty confused if a Russian was sitting on my park bench too.

Bear certainly seems to give a damn about man roaming nearby, though.
