7. When are you most unhappy in relationships?

Introverts can be picky in the people they are willing to be friends with. So, that would lead to them to be critical of the kind of people they are engaging in a deep connection, as they are indeed observant of others’ behaviors and gestures,

If you find out if someone is an introvert, make sure to give the best and most positive connection you could have. Just be lucky that the introverted friend of yours has not (yet) called your friendship as “toxic” since that would be diagnostic to their perception.
