Elder here. Never had a cell phone for years, wouldn't buy one, My first one was a gift from my brother and I duly promised to keep it charged and to carry it with me always. I did that for years and hardly ever used it. Most of the time it was turned off in my pocket. Then I bought my first laptop. It was hard to resist them finally and I succumbed to their siren call. Anyway tech changed the way I lived and I came to love my smart phone as well. Basically my favorite part of the phone is the camera! I can take pictures anytime anywhere and send them to my laptop where I can play with them. I love doing this. Taking selfies is fun. You can see anything negatively or you can join in and play the game. Giving likes to people you care about, is more how I see the issue. I like taking pictures including selfies. I take them of me. But I do think it is rude to take pictures of others and post them on the internet without their permission.
This selfie will self destruct in short order.
