Why was he standing so close to me?

My sister in law invited me and my mom over for new years tonight.My brother and his friend Mike weren't their when we got their but they came in after a while they were going out so Mike was just waiting on my brother to get ready. They had stuff to make sandwiches sitting around so Mike made himself a sandwich he kept walking around every room not sitting down. A couple times he would come and stand right in front of the sink which i was sitting at the bar across from were he was standing. I have a crush on Mike i was wearing dark blue skinny jeans and a black shirt that has black lace all on the top part of my chest.I don't know why he kept standing in front of me he didn't say anything. Maybe its because he didn't want to get any crumbs on the floor.
