People are forgetful by nature (especially with information they don't find relatable), so don’t assume hostility or disinterest if something is forgotten.

Most of the intentions behind our actions are hidden. If a person is feeling depressed or angry, usually the resulting behaviors distort their true feelings.

Most of the time you feel something, nobody else knows about it. So don’t get angry when people aren’t responding to you.

Don't assume everything is fine just because someone isn’t having a nervous breakdown.

We are social animals and we feel especially sensitive to any threats to becoming ostracized.

It happens when helping you directly or indirectly helps me. And our behavior is largely dictated by it.
