In what I have seen, the only time there is amicable departure is when the gymnast is quitting gymnastics completely. Then, you can have a party and hug everyone and they will say come back if you change your mind. More typical is if a gym even gets wind that you are talking to another gym, they dismiss you that day. So agree with everyone, pack up quietly, tell them on last day, text goodbyes after. I have read people posting about nice gyms who give you the blessing to go, but I have never seen it in our area.
