Oh, I can so relate to this, and it brings tears to my eyes about this poor young man.
I was waiting at the bus stop the other day when an elderly lady came up to wait too. There was something about this lady, I could tell she would try and strike up a conversation, even though we were both standing at a respectful social distance from each other, both ready in our masks as required here for using public transport. At the best of times I’m not inclined to chat with strangers, but especially not these days, feeling very weighed down with a lot of personal problems. I set my face to looking out for the bus, but sure enough the lady started engaging me, asking me if I’d been waiting long, remarking how slow the buses were that day, things like that. Fortunately my good manners kicked in and I replied in what I hope came across as a friendly manner (as much as can be behind a mask!), even ventured to say that I was on my way to the dentist. The bus came pretty quickly, and that was that; the seats are blocked off for social distancing, so people cannot sit beside each other. Afterwards, though, I was glad I was able to be friendly for that few minutes. Who knows what this lady was going through in her own life?
You are so right, goout, just a smile and a bit of eye contact and whatever follows with God’s grace, is all that is needed sometimes.
