Amazing really. You drop back a century and a half and you discover that some things are just the same.
The new telegraph, for example. Radical beyond belief, giving people the ability to communicate over distances of literally dozens of miles in almost no time.
It's so similar to the use of txt that I keep forgetting what century I'm in. I've managed to explain to my correspondents the concept of LOL and TBH. But there's a straight-laced lady in Woking who's not talking to me any more since I responded to one of her communications with LMAO. Apparently you don't say that these days.
