I take my hat off to you for doing a job which I imagine isn't easy - I know I couldn't do it, don't think I'm tough enough. My 23 yr. old applied for a similar job here last year, didn't get it, odds weren't too good - 6,000 applications for 40 positions! (applied for police work too, but there were 10,000 applicants for less than 200 positions!)
Oh, your poor little guy....and daughter...they grew up together!
It's so hard, you don't want to see him suffer but saying goodbye HURTS!
