I completely agree with you. Even though I think that something like writing a letter shows someone you care, I can also get that same thing through a text or an email. I am a few years older than you and I remember what it was like before email or text or social media. It was a different time but I have learned to grow and change with the times. (I have even brought my parents along for the ride!)
I think that it is important to know how to write long-hand and to communicate in more than emojis or 140 characters. I believe we still need to know these things so we have access to our history (i.e. Constitution). However, I don’t think these things need to be put on a pedestal — just in our tool bag.
