Hard as it may be for anyone under the age of 30 to believe, when I started work there was no such thing as social media. In fact, there was barely even email. I remember trying to send my first email, via a modem that kept dropping the connection. It took so long I ended up phoning the person who sent it and we chatted while I waited for the message to come through.
