I Saw an Old Friend of mine Yesterday...?

Sadly, he could, or he could have had some prostate cancer, or whatever...if you and him have made your peace, you don't have to hang with his 'friends' if it makes you uncomfortable,...but let him know in a nice way, without asking him about the status of his health,..that you will be his friend...in time, he will tell you the truth...God Bless him and you.
