So, for all of you following Silas' life, I think this video will be cause for joyous celebration. I don't want to give anything away with what I write here because it will be more fun if it's a surprise. I like to say that this was Uncle Patrick's birthday present from Silas (this was filmed at Patrick's birthday bash).
(PS. A hint for Grandma and Papa: He did this after I talked to you and said "no, he's not doing that yet.")
