I don't think anyone appreciates being yelled at. When it comes to older people, I try to give them the benefit of the doubt. I used to think they were just an old cranky person. Now I see there could be many reasons why they were cranky. Maybe they just lost their spouse, or their beloved pet. Maybe they cannot afford their meds, or food. Maybe they are trying to make it financially, and their not able to make ends meet. Most of all it sucks to get old. The aches and pains can make anyone cranky. They might be getting Alzheimers and think their life is over, as well as their mind. If this happened to me, I would say that vaping is not the same thing, and I appreciate their concern. Some of the old folks are just plain lonely. Maybe you would think I am old. I am 54. I am new to vaping myself. I know from what my father went through, that old age changes you. He was very independent when he was young. When he could no longer take care of himself, he became hard to deal with sometimes. So try to see things in a different light. There could have been a million reasons why this man went off like he did. He should not yell at people regardless. But at least you might see a few reasons, as to what might have caused the outburst.
