My parents will be attending a workshop given by T this weekend (workshop about empathy), so they will bump into one another.

Is it's OK to ask T a favor: that if the opportunity comes up for conversation, to tell my parents to stop doubting my life decisions, and to support and believe in me.

(My parents know I'm seeing T, they're the ones who gave me T's phone number in the first place.)

I know it's my responsibility to stand up to my parents, but still it may help if T could add a voice to support my path in life.
