Am I wrong to not help a friend
I f(minor) have recently got into high school and subsequently, marching band, specifically for colorguard. For context, I'm friends with everyone there and there hasn't been any drama until winter season. Back in February 26, a Thursday, me and my friend(a senior) are both and choir and had to leave practice for our choir concert. After the concert, I was just scrolling after dinner when my friend A texts me to call. I accepted and they proceed to tell me that friend B has told our captains and coaches that friend A was hitting them hard and that there were bruises to show. They also told me that they wanted me to "vouch for their character". At the time, I didn't know I was the only one they called about it. I did my best to comfort them but the following day on the optional practice, I didn't tell the captains anything because I didn't know how and unfortunately I don't pay enough attention to the things going around me. After this, friend A's relationship has fallen a bit with the others, I've stayed being friendly with them as previously before there wasn't any drama. I say friendly because they are passive aggressive and often don't take criticism too well, as one week before a comp they told captain A that they didn't know the riffle coreo and that nobody helped them despite my friend who is also in choir offer to help them just earlier. After that and other smaller incidents, I slowly distanced myself away from them. Am I the asshole for not telling the coaches and captains anything?
