Lost Ones

I found out Monday one of my former co-workers passed away.  I am still unsure of all of the details.  Bottom line is he is gone.  I've been thinking about him and his family all week.  My biggest concern is his kids.  They loved their father.  I know this is going to be hard on them.  It really made me think about the time I spend/don't spend with my kids.  I really need to start being a father and not just a financial provider.  I don't want something to happen to me and end up regretting time I could have spent with them.
