I love the way you tends to relate with your nephew, that is how life should be, when you make him feel your presence, and just as you have said, long after you have gone, he would be remembering every piece of play you used to have with him especially "Lego.
You might think your nephew has not missed you but have you tried asking the little man himself if he has not? He must have missed you too.
YOUR Lego creation are awesome, the last one here has a caterpillar design.
He misses me a lot and he says so; he's a good kid. We video chat each week and have some fun and good times, but it's not the same as being with him in person. I feel like I'm missing out on a lot of his life. Still, I'll take what I can get.
Wow? I know that feelings.
