i walked up to him and asked him: do you have a moment to spare?
he said: wait a while...
after waiting for a bit, i just walked away.
i walked up to him again after some time, and asked him the same question.
this time, i also asked: are you busy?
he said: yes, very busy.
after that, he was sorting his stuff and i walked away again.
i thought: i don't have to say this. it doesn't really matter i guess.
so i walked away, without telling him that i am missing him.
