I can't whistle, I'm in my late 60s and have never been able to whistle, I try, I do whistle, but its barely audible. There's only me who knows when I'm doing it (sad face :()im going to whistle on Tuesday, always thought we needed a change, and I think whistling is better. Watch someone reply Boo now!
Will it be okay if I just boo like always, I'll feel much happier doing that. (happy face :))
