This is the sort of take that just sounds entitled, because the person giving it is doing so from a position of not having discomfort created for them by the actions of someone else.

Like let's put this in context: replace "being an introvert" for "your friend flies you out to the forest, and then happily announces we're going to be hiking 20 km back to town. You really need to challenge yourself!"

Your replacement only strengthens the parent's point to me. Sounds like a fun little challenge that I would love if one of my friends gave me. I wish I had friends like that.
