Answer:
If someone has a difficult temperament, that could mean they have anger issues or they're extremely isolated, it's not really clear. However, what is clear is that trying to relate to people who have extreme emotions is very difficult. They might burst out at you, or not respond to you, and because of this, it can be very difficult to have a conversation. If conversing with them is hard, then building a relationship is even harder.
