When i found out something off-putting about my t, the consulting t i spoke with just asked me if i felt i could still work with him, if he could still help me, even if i knew he wasnt mr perfect. I think the same think kinda applies here. We are all just human. From what you have written, there may have been some very minor misunderstandings, but nothing ever actually happened. So its like having a second chance to think about what effect a past teacher or coach actually had on your life, now that youre older and can understand and appreciate it better.
