Hi Ron,
I'm very humbled by you taking my phonecall today and kindly having time to chat reference your spreadsheets. You have evidently spent a lot of time & effort in creating and updating these. The information within is epic.
I intend to set aside some time this weekend to get a grip of the content.

I'll be back in touch soon and I wish you and your family all the best and a good return to health.

Pauldola.
