Rest in peace Bosco

My boy passed suddenly yesterday at 12 years old . I keep thinking I should have noticed something different that day but he seemed like himself. He came to see me I was working in my office and he layed by my feet for a bit. When I got up he did too he took some steps and just suddenly stopped looked down and labored breathing and within half an hour he was gone. I was able to be with him and hold him until he passed...I just wish I had another day.
