I have two kids who I love very much and always try to set a good example. Recently, I’ve been feeling a lot of guilt about a particular time from when I was a kid. I was about aged ten (or perhaps younger than that), and I was going to a five days holiday camp. During this week, I made friends with a girl. I think she had a crush on this guy called William because she would always try to involve him in our group. Now of course I realise that I acted appallingly, but back then I wanted her to be my friend and my friend alone. So for those days I tried to get her to hang out with just me, and teasingly called him the nickname ‘Willy’ (I mostly said it to my friend behind his back, I cannot remember if I said it to his face or not.) My friend gently told me not to say it once, I don’t recall him saying anything or complaining. I just feel really guilty about it now- was it bullying? I have no contact with him now of course because it was only a 5 day camp and it’s been many, many years since, and I have no idea how to make things better, other than trying to teach the importance of compassion to my own children. Any advice?
