The 1st Day of Kindergarten!

Would it qualify me as nuts if I told you that I have tears in my eyes just looking at these? This day may very well qualify as the saddest day of my life, thus far! Okay, so it was bitter-sweet (heavy on the bitter!), but I may have cried myself out of tears that day! My little Mason grew up overnight! How does that happen? Is there a way we can push "pause" so that we don't miss anything? I truly can't think too much about it, or I go into depression. I love this kid! He's been my best bud for as long as I can remember!
