Hi. I've had this good friend for 11 months. We've been gradually getting to know each other and just having fun. I did something that really upset him yesterday and he just won't communicate. Here's what it was. A few weeks ago were on a group walk, relaxing in the sun, and he splashed water over me. It was a laugh. I said' 'I'll get you back for that' and it was all fun. Yesterday was the next group walk. I brought with me a pot of dry sheep muck and poured it over his face. I said it was payback. I really thought he would laugh. He didn't. Gave me the silent treatment all the way back. I told him I was desperately sorry, hadn't meant to hurt/upset him, was meant in fun and wished I could undo it cos I deeply regretted it. Told him he meant a lot to me and was gutted I had done this. He seemed to thaw a bit and said 'OK I hear you but just don't say any more' and we had some general chat before we went our separate ways. He lives at a distance, doesn't like phone, so I emailed him when I got home and said again how sorry I was and also said a few general things, to show I was listening and trying to draw a line under it. I've heard nothing since and am so worried he is going to just end the friendship. What can I say that is brief but on target and will help save the friendship?
