yeah but what you're saying is unclear.

for instance, when you say because they have to, not because they need to...

"have to" and "need to" mean the same thing, so i'm left with the choice of concluding your post is just mush or asking you to rephrase what you're trying to say in a way that's intelligible.

Perhaps I should have written "because they feel they have to and not because they need to."
