suprising coincident.

I'm Ladidi About 3yrs back a guy (Peter) walked into my office and asked me to help him with Microsoft Project, I offered him the assistance he needed and afterward I saw him once in a while and didn't see him again. During those periods I saw him, all we did was wave at eachother. Recently my department conducted a training where I was a support-facilitator. Suprisingly, he was one of our students, after the training he offered to get me lunch but I wasn't all that interested but he made sure we exchanged numbers. During this period I was seeking another job and applied as a Research Analyst at an Investment Bank, please note that I have a science backgrounnd being a computer science graduate but I was desperate for a new job so I applied in faith. After 3wks I got the job but as a project manager of the firm even though I didnt have prior experience in project management. I kept Peter abreast of my new job and he asked where my office was located and when I told him he said his parents live next door and they let out my office.I didn't believe until I resumed at my new office and he waved at me from his house. During one of our conversations he told me where he grew up which also happens to be the same place I grew up as a child but different street. Does these signs mean something for both of us? Our lives are so similar I keep wondering what these mean.
