The answer I got was: "I'm on Snapchat!"
Oh, of course. Silly me.
"Why don't you download it?"
"Why would I want to keep taking pictures of myself and sending them to people?" I asked.
"Because it's fun. Anyway, the picture and chat disappear once you've read it."
Anyhow ... I've finally succumbed and downloaded Snapchat onto my phone. My daughter had to give me an in-depth lesson on how to use it - all the funny faces you can do with it, the video shots, distorted voices, and the messaging.
Before I knew it, I was really enjoying it. My grown-up daughter also has it and sends Snapchat pictures of my baby granddaughter which are hilarious (poor child).
I don't think I'll be Snapchatting anyone other than my daughters, as it would probably confirm my friends' views that I've finally lost the plot!
So, the point I'm getting to is that love it or loathe it, it has turned out to be a fantastic way to keep in touch with my teenage daughter. Historically, when she was away from me with friends or her father, I could never get any response from her by messaging, WhatsApp, email, phoning ... but with Snapchat - she always answers within at least a few hours (that's good believe me!) as she wants to keep the 'streak' (? or something) going which means you have to Snapchat that person at least once a day ...
