There is the feeling that you get when you are vaguely and aimlessly thinking of someone and how lovely they are in general and suddenly a memory or thought comes of how lovely they were or are in specific and you find you have breathed in too far as if you were in some kind of pain and that if you want to continue to function more or less normally you are going to have to breathe out very slowly and carefully because the heat that is rising between your neck and your belly is going to burn you otherwise.
And then there is the feeling you get when you are vaguely and aimlessly thinking of nothing in particular and you remember that something is over now and you find that you have breathed in far too far as if you were in some kind of ecstasy and that if you want to continue to function more or less normally you are going to have to breathe out very slowly and carefully because otherwise the thing that is sinking somewhere between your neck and your belly is going to tear you apart.
And you wonder why both of them feel like crying.
