I understand from this question that the initiator of forced movement can choose not to move a target if they wish, but if the target is an ally, is the ally able to choose not to be moved?
I am going to start playing a Bard soon, and I thought that it would be good to know in advance whether my party members can veto all of the sliding that they will inevitably undergo. I don't plan to abuse my power, but if push comes to shove (no pun intended), it's nice to know who gets the final decision.
