Can anyone give me examples of people actually being nice?

Honestly, people really do feel like the worst. Everything from just being rude, to being actively hostile. Supposedly nice things usually end up bad. Friendships are transactional. Partnerships end up toxic. Someone could compliment you to your face and you'll always hear later about some sht they said to someone else about you. You hear people saying awful things about others, go on the Internet and you'll see people shtting on others for just existing.

Does ANYONE have example of pure niceness? Anything that makes going out and meeting people worthwhile?
