Due to both my mental, and physical issues – I have no social life. Once in a while, I might go to a restaurant with a friend, but even that becomes a challenge. When I need to address errands, I typically do things as early in the morning as possible. This limits my social interactions. I correspond with people on the Internet, and even do email which seems to be a lacking feature for most people. I write to a couple of people regularly. I also use Signal, and Telegram.
When I go out into the physical world, I will carry contact cards as a just in case someone wants to reach out to me. On the contact card will be a QR code pointing to my contact URL ( http://fsp.tel/ ). Under the QR code is my name, toll-free telephone number, and Contact URL ( printed out ). This allows anyone with an internet connection to get more contact details. On all of the pages of my sites will have a link to a VCF which will import my basic contact information into your supported phone.
