@jespah,
Also, I doubt Barb took any notice of what you looked like. You're both beyond your 20's, and both of you know what a human body looks like, warts and all.
Alternatively, you can imagine what it would have been like if you didn't call her on the phone and had to lie on the floor in pain.
Agreeing with the others. Barb is a good person. It's good to know you have someone you can count on.
I'd also go to the doctor about those cramps.
