Sometimes I'll see someone on the bus or something who is really beautiful, has awesome makeup, or is wearing a really sweet outfit. If I really enjoy it, I will try and sneak looks. Sometimes I will outright stare, and if they make eye contact I'll smile at them. I always love it when people smile at me. So I really don't care if someone is staring at me. I try to assume that they are admiring something, but either way it really doesn't affect the rest of my day unless I get a smile, which makes me happier.
Why does everyone have to assume that other people have the worst possible motives? If there are a few options for reasons why someone is doing something, why not assume the best one is true? I try to, and it makes my life a lot happier.
