<human>: Last week, there was a work function at night. Two of my coworkers came, let's called them A and B (both male) and two other coworkers bailed. A & B also bought two senior mngment workers from out of state who came to visit (also both male). So when they came in, I was really excited and happy to see A, who smiled back and stared back. I was nervous but wanted to approach him but it was a networking thing and other people came towards me.

A was talking with some other people, so I went to B and started talking to him for a bit. Afterwards B and I didn't have much to talk about and he said he is going to go talk to someone else. At that point, I decided to approach A's group.

A introduced me, and the two seniors were cordial towards me and started asking me questions. A was smiling and kept praising me. While I was talking to the two seniors, whom I gave most eye contact with, A and I gave each other glances. But one of the seniors kept smiling and looking back at A and me.

I tried not to look at A at that point, because I felt like the senior was wondering if A and I slept together. A said something nice about me and then I thanked him and was still talking to the seniors. IDK why that one senior was smiling at the both of us so much. They said it was a pleasure meeting me, and I left to go back to my seat.

A and I didn't sleep together etc, just for notice.

What might have been the reason the senior kept looking back at us?

Can you condense the text into three sentences or less?
<bot>: Seniors gave A & I smirks while I speaking to the group // Why did the senior mngr smirk at the both of us?
