Dude this might come off as overly corny and not trying to be but those pictures touched me a bit and just had to commend you! I know it wont seem like it now but you just created memories in that young man that he will always cherish and there will be one day when he sits back and just smiles thinking about that trip.
In no way did I have a great relationship with my dad. Most memories are bad ones but the few good ones I have are of us at the drag strip working on or setting up one of his cars and all the side stuff we would do on the weekends.
Good for you sir!!
