Irrational Acts-
People are mostly good, but don’t assume everyone is rational all the time. A person acting irrationally will do things you don’t expect. Including things that hurt themselves, so long as they hurt you in the process. There’s no limit to what the human mind can justify to itself.

If anything in this world is unpredictable, it’s people. Including people you think you know well. Because we create models in our mind of who we think they are and those models can sometimes be very inaccurate.

Nobody reveals everything about themselves and people change over time. We also don’t get a chance to see how everyone is in every situation. Certain situations bring out different parts of a person’s personality that might otherwise remain unknown (sometimes even to them).
