Whenever I wanted to keep in touch with someone growing up, I’d ask to exchange phone numbers. I still do. This habit meant I didn’t really need to use social media to honestly keep in touch with most people. At most the social media would hand me a quick life update (e.g. vacation picture lets me know to ask you how your vacation was) that I could use to start a conversation. I think this worked because most people my age had cell phones that they accessed the social media from.
