I actually remember a time before mobile phones and the main difference that I remember is that you had to be at the place you arranged to meet at on time and where you said.
Mobile phones are magical things and our whole lives are in them but we have lost side things such as printed photographs, postcards and letters. Our text messages, gifs and emails won't be found in suitcases and keepsake boxes by our grandchildren in years to come, they will all probably be in the block chain for all to see and maybe that is better
