Yes, it is a small world...my friend of 49 years was dx back in the 90s or so...we never ever thought I would have the same dx a few years later.

We also have a guy we went to school with dx in the 70s...yep, for such a big place it sure can be small.

Glad you do get to spend time with your friend, maybe she needs to know you have more in common that she realizes.
I'm open with my MS...if someone notices the cane or me holding on to a buggy just a little too tight. I feel it gives one the chance to be a little more informed about MS and I sometimes get them to donate to the cause from just a conversation.
