There are many things that you thought must continue in the next day; there are many persons that you thought must present in front you again in the following day. That is why all in your mind is simply the hopes of reencounter (even no feeling of such a little hope sometimes) when you put the things aside just for a while or you shy away from somebody just in a short time.
