Arthritis Can Create Awkward Situations

Some aspects of arthritis cause very visible problems, easily recognized and understood by other people. Arthritis also can lead to situations which are nothing less than uncomfortable and awkward. Here's an example - have you been in a grocery store at the checkout, slowly and painfully taking each item out of your cart while the people behind you in line stare and look tormented by what is taking you so long. Wish that you could make them understand? What should you say?
