Sometimes I don't know how helpful I should be, taking in account I am new to the sport.
Yesterday I was looking some people fly and one guy was struggling with the way he connect the wing to his harness, first I was looking and I did say nothing, but when he prepare to inflate I saw something was not right and I told to him. He checked, disconnect and connected again wrong, after a while I connected his wing to his harness for him and asked him to check everything and don't trust in what I did, he checked and took off.
Later I was thinking what happened if I have connected his harness wrong and he get hurt because that, but if I did say nothing and he took off with the harness connected wrong and get hurt ?
Is there a line where I should not cross on help others ? Like I should told him it was wrong but not connected for him.
