I get the gist of both and the differences between the two.

For soft next, I've seen members on here say it's for a limited amount of time (two weeks or so) others have said don't say shit until she says something, and then act like nothing happened.

What determines in your eyes to soft next vs hard next?

Do you factor in how long they were a plate for, the fact they may have a boyfriend/married, so if they are flaking you're more open minded about it and or don't "punish" as swiftly?
