Thank you for acknowledging that, it really means a lot to me. What made you react that way though?

I don't know, I guess I just felt embarrassed about what I was wearing. But that's not an excuse for my behavior.

I understand, but I hope you realize that what we wear doesn't define us. And remember when we went to that restaurant a few months ago? We had such a good time together, I really enjoyed talking with you.

Yes, I remember that night. It was great to spend some quality time with you.

Yeah, and I think it's important for us to continue doing that. We can have some fun and forget our worries for a while.

I completely agree. And going forward, I promise to be more mindful of my reactions and not let my insecurities get the best of me.
