Bobbie wrote in to let me know that she talked to her daughter's teachers. Her daughter is one of the most prepared in the whole class, so it was no problem for her to be out. So they went to visit Bobbie's husband with no worries. Yay!
Sheila C sent me the link to this article about an enzyme present in the blood of people who died from peanut allergies. It may be a way to tell who will have fatal reactions and who won't ahead of time. Very cool, and why I love science. Thanks, Sheila.
