Having noticed people making good use of wait time by using their phone, I admire their productivity. Back in the day, waiting in line was cause for simple reflection and recollection, or friendly face-to-face conversation.
Nowadays, phone calls to automatic answering services (a misnomer in my opinion) and waiting for a friend (as I write this), are opportunities for my journaling on iPhone Notes, planning on Calendar, messaging, copying to a Gdoc, or adding to a Gsheet. So, wait time is welcome. Bring it on … with or without a phone.
