I'm very sorry for hurting your feelings while we were at {event/location} on {date}. I didn't mean to {make you cry/upset you/make you angry/etc.}, and I hope you know that I would never intentionally do something like that. I've felt bad since that day, knowing that I've caused you so much pain.

I hope you can find it in your heart to forgive me. I value you tremendously as a {friend/colleague/sibling/etc.} and I want nothing more than to get our relationship back on track. Please let me know what I can do to make it up to you.

Sincerely,
