There is a guy I walk past on my way to work in the mornings. Over the last 10 months I'm sure there has been eye contact and a flash of something between us. One of my friends said when we walked past he's looked at me a number of times. This week I plucked the courage to go up and buy something of his but he didn't make any conversation 
How do I make him notice me? I always make the effort with my clothes, make up and hair. He's gorgeous and maybe seems a bit shy. Help
