A colleague always laughs at me for being short and makes me feel uncomfortable. Boys 2 1 172cm know how to let go of their short stature.

That boy, 2 1 172cm, is the one who laughs at you for being short? In fact, there are no perfect people in the world, but everyone has shortcomings. If you are really short, you hate being laughed at like this. You can also tell someone else's shortcomings in a joke, answer blows with blows once, and maybe it won't happen again.

If the boy you mean by 2 1 is you ..., you really don't have to resent others making such jokes, because this is normal height, and you can ignore others' jokes. Feel free to do what you should do.
