He looked at the floor and smirked?

Hey guys,

at my school we have some IT-assistans that help us with computers and stuff. Two weeks ago, I had a problem and this IT specialists guy helped me out that afternoon.

Today I was walking down the hallway and he was coming opposite me. I saw in his eyes that he recognized me and then he looked down the floor and smirked to himself. 😏

i am scared i looked funny or he thinks badly about me.

please y'all help me and tell me what it COULD have mean and why he was smirking?
thanks !
