I feel like this old rug has been beat to threads. But I have volunteered for my entire life, so not doing so just feels wrong. Am I volunteering for free author school visits? No, to that. I ought to be paid for those. Am I volunteering in our public library in November to run a NaNoWriMo Young Writers Workshop for six weeks? The answer to that latter one would be yes, for I will do anything I can to help kids (and adults) to write, and write better.
Okay. You may beat the rug if you like. What are your favorite volunteer activities? (As long as they do not interfere with your own writing, that is.)
