What does eye contact mean to you?

Hey y'all!! sooo this morning at work ( I work at an daycare) a DAD dropped off his son and after started walking towards me.. well he seen me and immediately started staring at me.. I mean this wasn’t a normal gaze then look away this man stared deep into my soul. It felt like... So of course I smiled at him.. lol and HE didn't SMILE BACK.. so yeah talk about AWKWARD why did he stare deep into my eyes and not smile back?

Update!! This morning we had eye contact definitely longer than seconds AGAIN felt like he was staring into my soul 🤣and he Smiled and said “good morning” to me!! What possibly changed from yesterday lol

Also I’m (F 26) He’s maybe in his late 30s early 40s!!
