There's a kind of person. They secretly hope that someone will do something for them, most of the time it's a small matter, e.g. ask how are you doing recently, offer a coffee or tea, ask to be careful when crossing roads etc, those little caring actions. When their wish wasn't fulfilled, they will upset with that person secretly in their heart, thinking why couldn't he/she do that, while making excuses for them.

Isn't that funny and sarcastic?

So, to prevent this, stop expecting people to do things.
