Am I stupid .

it wasn't until I read back through the whole post that I noticed you mentioned having leg issues.
If I had read more carefully I might not have made the comment about standing on the bus. it was not meant to be insensitive to your situation, and if you found it offensive I apologize.
Never entered my mind , I realize you only meant to help , besides I have thick skin or am dense and things go right over my head , take your choice .
