Well done on your running, keep it up, just think back to how far you have come in a short time!
As to acknowledging others:-
I always make a point of smiling and say Hi as I pass people. I also say 'excuse me' if I need to pass them, then 'thank you' when passed. So far I have found when out running most other runners do acknowledge me, even if it is just raising their hands in greeting. The other week one group of men were running the same circit my husband and I was but in the opposite direction. When we passed again further round they laughed and said 'have we met somewhere before?
If people are so ignorant and don't acknolwedge us as we run by then it's up to them, at least I know I was friendly.
