Why does my crush look down when I walk past him?

He was walking towards me.. , I had my phone in my hands was about to text , We made eye contact , he looked down stared at my feets/shoes then we walked pass each other silently. But that man literally walked me over off the road then I started walking on the damn grass.šŸ˜‚ what is wrong with him? Why this behavior?
