I have an old buddy who lost sight in one eye several years ago. I can't imagine such a thing but he took it in stride, and with humor. Dark humor, but humor nevertheless. Never a pitying word.
I met him driving on the road one day and waved vigorously for him to pull over so we could chat. Went on by with never of a hint I was alive.
Next time we talked, I admonished him, "damn Vic, I waved my arm off trying to get you to pull over, and you just ignored me" !!
He grinned right big and said, "nah R, I won't ignoring you, but I only got one eye, and when it's driving, it's doing all the looking it can".
He was a great volunteer for youth sports, and even did some baseball umpiring. Yep,...that's right.

One night I was watching a slam-bam play at the plate and Vic made a bad call.
The opposing coach came raging from the dugout, steam jetting from both ears, and at the top of his lungs yelled, "ump, for Christ sakes you must be blind" !!!
Vic calmly raised the ump's mask up and turned that pale blue sightless orb at the coach and said, "cousin, you don't know the half of it;.... now go on back in the dugout and keep your ball players company" !
We all have to endure some hardships in life; but I tell ya, old Vic has a little harder bark on him than most..... me for sure.
