There have been several moments he has looked in your direction as you have pulled into a parking space at your apartment complex.
He has done this enough times that you know he isn’t oblivious to you and is fully aware of your presence as a neighbor who lives a few doors from him.
You sense his eyes on you, yet whenever you move to look in his direction, he avoids making eye contact.
Even when you have been in situations where you see each other by chance in the hallway, he might acknowledge your presence quickly with an awkward smile or muted hello, but he walks past without slowing down, not attempting to open a conversation with you.
