I got the idea from a friend who was talking about how we communicate different ways in different media, and the first thing that popped into my head was how we type “lol” when most of the time we don’t actually laugh out loud.
On the internet, “lol” is practically a verb, to the point where “lolling” and “lolled” are used as actual words (“lol” is also used as a noun, with the plural form “lulz”). But you would never actually say anything like that out loud without getting funny looks, unless you were actually among friends who are also enveloped in the internet culture and you were talking about something you found funny online. And even then, it’s a little awkward.
It’ll be interesting to see how much our language changes over the years. The internet is still relatively young, and there’s a lot more to come. I just hope I can keep up enough to understand my kids someday!
