Thank you! My mindset and approach as well as open attitude have managed to give me 54 beautiful years on our planet so far, and I have no intention to draw my last breath yet. 😉 However, I ask myself, what is most dangerous. Mind, that I did not approach him as you post. I was sitting down, calling him over. If I would have walked towards him, he might have felt scared and the need to protect himself from an unknown threat.
In this situation, my evaluation is that it´s more safe to just sit down, as he is not after me. If he starts shoot, it´s more probable that the one he aims for also run in panic together with the crowd and a stray bullet could hit me. The only thing me calling him over would do, according to me, is calming down the situation.
