they can't move forward without closure, and it's usually because they feel entitled to either speak whatever is bothering them OR they want an explanation on why things happened and can't accept that some things you will just never know. If it's closed, then let it be closed. If it's over, let it be over. but some ppl press it and their lives depend on it.

but i can't tell people what to do, if they want to get closure then fine but I guarantee it to most of the people seeing closure that the other person is doing fine and moving on without you.
