What should I say?
I found a friend's email on my phone, and I haven't seen her for a couple of years. We lost contact when she went back home from her visit in the summer and then me moving away a couple months later. We exchanged emails, but I put hers in my old phone, and when I moved I had to get a new one; I was just playing around with my old phone and I found her email. What should I put as the subject? "Old friends"? I have no idea what would be appropriate.
