During the first 5 years of my life, I grew up with a boy. We both had the same babysitter.
We played together in parks and sandboxes,... We were like brothers and sisters. His name was Matheo. One day he stopped coming after school at our babysitter. Overnight we have never seen him. Neither my parents nor my babysitter knew what happened, and where he and his parents were gone.
Today with all the means of communications I would find him. But I don't know how. I already try with facebook but it has nothing to give .. Someone just give me some ideas to conduct my survey?
