I did it this time

I think I have done it this time.  A Friend and I took the grandkids to a movie.  The grandkids and I went to one movie, while Friend went to another which got out 20 mins after mine.  After the movie got out, the grandkids and I went to the car and since it was in the sun, we moved to the shade. We waited and watched for Friend to get out, but did not see Friend.  So we sat in the car till 9pm waiting for Friend to come out.  At 9pm we left after a text that we were leaving, but I would be back for Friend after the movie got out.  I brought the kids home so they could spend the night with a relative and went back.  When I talked to Friend the next morning Friend said I passed Friend the next morning, Friend said I passed Friend on the freeway.  I honestly did not see Friend or I would have stopped.  Now Friend is avoiding me, and I don't know what to do!
