As a divorced father who lives 3 hours away from his kids, it is always tough to keep connected. Well when I filled out a bunch of NPN for myself, I did the same for my son (just turned 16), at his house.
I talked to him two nights ago, and then he asks if I sent him a card. I asked him who it was and then to describe everything on the card. Well it wasn't much 07 Elite Back to the Future Warrick Dunn/Jerious Norwood /250.
I thought it was very cool, so I explained to him what NPNs were.
This is the best NPN I have every received, just because of the connection for me and my son.
