Role-playing/modeling might be a good way to practice how to kindly decline playing with someone. It's a very beneficial skill, and necessary for not getting yourself pulled in many directions socially or in future jobs (knowing when and how to say no). Learning that you can set boundaries but still have friends. Frankly, I have always veered away from any friends that put outright demands on me or expected that I should put them ahead of anyone else. As an introvert, I don't want to feel obligated to socialize. On the plus side, it's nice to know you're wanted and liked; it's just healthier to know how to set your limits.
