We've all been invited to a child's birthday party, with that little invitation inviting us to celebrate a milestone of some kind for their special little one.
A 10-year-old walking on a subway platform in Milan, Italy while playing his handheld PSP became so engrossed in his game that he wandered right onto the train tracks.
The youngster took quite a tumble, but Alessandro Micalizz, an off-duty cop, immediately jumped down onto the track and pulled the boy to safety. The next train was less than a minute away.
No word on what game the boy was playing.
