@nan415 I agree with @buuzn03 and the others - most schools have parent volunteers who reach out to be a resource to you. Don’t feel like you have to engage with any of them… I have had LOTS of parents reply to me with a simple “thanks, I’ll reach out if we have questions”, and that’s totally fine. My main role as a volunteer is to be here if you need me, and to give you our perspective as a 2x parent, not to convince you to come, though it sometimes is hard to NOT do that! 
Oh, and my school is Mercersburg, should you ever want to reach out via PM.
