People approach and bother other people when they themselves arent relaxed and spot a relaxed person in public. Especially elder ones emotionally dump/bother younger people.
Also, when you are alone you are an easier target for other people to approach and “bother” you.
It seems that the better your health and vitality and physical apperance is the more you have to protect yourself against other people.
And also alot of elder people like to get on your nerves, ask questions that they know will trigger you.
This is what i observe daily where I live.
