Uh, Thanks!

Speaking with my mother- in- law is always interesting. She has been chosen as a first responder should a chemical/biological attack occur. Apparently she will have a kit to treat herself, my husband, kids and myself. After what seemed like an eternity for her to explain everything she took a big breath which was followed by an incredibly long awkward silence. Exactly what should one say for the possibility of a potentially life saving gift should something horrific happen? Uh, thanks!
