Adam didn't want to give any more of his time to that old lady, or she would start blabbing about things Adam didn't want to hear about.
As he walks out of the building, he sees a few kids standing around his car, touching it, admiring it, clearly fascinated by it. Adam smiles and walks up to his car and unlocks it.
The kids immediately step away and watch Adam enter the car, wondering who he is. When Adam starts the engine and drives out, he sees the kids giving him a chase to the end of the road before stopping.
Seeing this puts a smile on his face, as he envies these kids for living their childhood, having friends, and playing with them, something Adam didn't really get to do much of.
He did have childhood friends like Lana, but that was when he was barely six years old. After the death of his mother, he stopped having friends, and the ones who did claim to be his friends only pretended to be his friends because of his rich background.
