<p>Everything is relative; during my school days, I would send an “Aerogram” (wonder if the post office still makes those, and if they do, who uses them) to my parents. I would cram them with text in a miniscule font, perhaps once a month, with explanations like, “there are things on roads in the US called exits …”, and that was more than adequate. Today it’s text messages multiple times a day, or something is amiss.</p>
