You shouldn't have to. If they push, you're a volunteer for my clinic. The intricacies of preparation aren't something you'll have to know for that.

[after all, the volunteers did different work depending on what they wanted to do. some just helped with delivery, some with repairs...]

And...thank you. I won't be able to say it enough for assisting with this. Finding the source on these leaks is actually very, very important to me, so I can't help but be grateful for it all.
