Dear Person Who Asked Me to Volunteer at School,
The problem is if I say yes to you now when I’m feeling charitable and have a light schedule and the sun is streaming in the window that does not guarantee that on the date 12 days from now when you need to count on me being chipper and active and fresh that I won’t be miserable running late juggling a deadline and resentful of all the other mothers who have no job and plenty of time to wash their hair and volunteer so I am saying no.
verysincerely
