Fast times

I keep seeing posts that say, "I'm on a social media fast." And I wonder how could they be posting when they're fasting? Isn't that kind of like saying, "I'm going to start fasting as soon as I finish this bowl of cereal!"? It's probably just me...

Did you also notice that Pres. Nelson challenged the youth to a seven-day fast. He challenged the sisters to a ten-day fast. What's it going to be up to when he finally challenges the elders?
