0-10, I have learned from email for the past 20 some years to be very careful who gets my phone number and damn few people get it

Didn't get a smart phone until after I retired. Told them at work that my old flip phone didn't do text. Saved me from hundreds of "to all" texts that didn't apply to me. If they really needed to get a hold of me they did have my phone number.
