People usually don’t see me angry. When I do, it would be because of the frustration of things I dislike built up over time.
My tolerance is high, so that means it would take a lot for that to happen. Of course, understanding the situation is also a contributing factor too, but it does built up faster if the anger of others are directed towards me.
If it to someone I had known for a while, it is usually for the things that has been accumulated over time that I had previously tolerated, but the most recent being too much.
Example: once in a while is okay, but too much of it is unacceptable. Maybe I’ll let it slide if enough time has passed, but if done again before then, my tolerance level is pushed closer to the limit.
In other words, try to tolorate, but if if kept pushing towards the limit, let them know. If enough time has passed, but still no improvement, it would be better to move on instead of still holding on.
