Evening all.
griff, I hope your dad is OK.
We worry about our loved ones. In my case it's children and grandchildren now. Maybe they worry about me. One or two health scares. Cancer having been one. The colitis can be a bit of an inconvenience - no pun intended. Life is.

Pretty much a normal day here. Pretty good weather. Walked a lot. Almost nine miles. But it's so easy with Max. Few commands. We go out by the front gate and he glances back to see if it's to be left or right. A nod of the head is usually the only signal required. And off we go.

Thanks Besoeker, I hope he will be o.k too, just worrying that they can't find the source of his stomach bleeds.
I have a couple of friends with colitis so fully understand how painful and inconvenient it is

Yes, the not knowing is worriesome.
