I have the same opinion -- I'm fine either way!
I've received corrections - and I welcome them, and I've encountered reading, but never have felt comfortable sharing it.
I think there is one person with whom I would share the correction privately too - only bc she has helped me, so I feel she would be open to it.
I fear another could take it personally - and I would rather not. Plus, I'm the last one to correct it! LOL - who am I to say that their "error" wasn't done on purpose?
Great writing Grace -- good to be reminded of how others see this! Thanks for sharing with us!
