Talking to Kailen/Growing Up

I talked to my nephew, Kailen yesterday and he was absolutely shocking. I had NO idea that he could formulate sentences as well as he does and all. Last time I saw him he was a baby, and now he told me that he was 6 years old. All my nieces and nephews are catching up to me. I have a niece in College now! College! They are growing, that's for certain! I really felt sad when he told that he did not know who I was. I wanted to be the Uncle Travis that is dedicated to spending time with my family, but unexpected circumstances came up/finance issues, etc. so I was not able to be the type of Uncle that I had anticipated on being. I really felt disappointed in myself in that aspect. But I intend on changing that and hoping that I can be more involved in my family.
