kaveh had a very busy day. he slammed the door behind him as soon as he entered the house. he didn't even say hello to you, he went to his office to finish his work as soon as possible and finally spend the rest of the evening with you

"i'm working, don't you see?!"

he said it with annoyance when you offered him a cup of tea. you were offended, and it seems that Kaveh felt that he would have to apologize later
