That takes place when you need them more than you want them. Desire and need are two different things; one ends and always changes, the second never dies and always renews.
Think of family, at times you might not want to be there, but you’ll never stop needing them. That’s how someone becomes home to you.
Even though desire has flare, it goes out eventually. Need on the other hand has endurable substance that way.
My writing sucks, doesn’t it? I should get back, soon..
