history: I recently had surgery for a kidney stone.  I am so thankful for my wife who took such good care of me after the surgery.  I was under her care for two weeks, but she was so considerate to all my needs.   I hope you never have kidney stones_comma_ but I have had several.  A month ago_comma_ I had to have surgery because one was lodged and was too big to pass.
current: Ouch, that sounds so painful!  No I have never have them.  Do you know you can avoid them in the future?
next: No, I wish I did.  But, in spite of all that, I have such an awesome wife.  She took care of me post-surgery.  For over two weeks, she was so considerate and helpful to all my needs.  I was down, but she really helped me.
