I consider myself extremely lucky I met my wife before the instant messaging era began. I spent hours, sometimes days, crafting sms text messages. Adhering to the charachter limit, making sure every word mattered and conveyed what I wanted it to, and have some meaningful message to send, riding my bike to the store to top up my phone so I could send some more texts…
Teens these days have no reason not to be online and connected all the time. I imagine the whole dynamic of texting with your crush (the way I experienced it) is completely gone. I have fond memories of those days. I pity my kids for not being able to experience this.
