Yeah he is so handsome...
You must hold him in your bosoms and tell him that every thing will be fine...
You can't do anything about stolen bike but take this opportunity to teach him some important lessons/values...
The most he will learn is from your reaction, so I suggest you to be graceful instead of being angry about theft/thief...
PS
If you can't afford a new bike, may be we can ask steemians for help...Steemians are so awesome when it comes to things like this. I am recently running a charity for a widow's family and I was really surprised to see peoples response...
