The dumbest thing I’ve ever done in my life:

Trying (through communication) to make others understand me.

The second dumbest thing:

Thinking I could actually understand others.

The third dumbest thing:

Encountering a preconceived misunderstanding and actually trying to explain myself.

Since I’ve admitted these are stupid things, of course I’m not trying to blame others — it’s a sudden realization: how could I have had such naive, twisted expectations and fantasies? I was so unenlightened. (Writing this post is pretty dumb too [facepalm])
