Feeling the effects

Funny how you find yourself in a not so ideal situation and you have to just work through it, get used to it and work around it. Let's say there are people who affect or even contribute to this. In this case, we'll call them Person A. Person A then finds themself in the same scenario you were/are in, and has a rant about how frustrated and annoyed they are. Cue the next day when they do it to you AGAIN. I guess sometimes being in the other persons' shoes doesn't get the point across.
