But just so you know:
On a random Sunday morning, if you tell someone you are quite sick and thus will not be at church, and then you show up on Facebook 3 hours later at a venue or having a meal out somewhere?
It shows up - on lots of folks' pages.
And then those other folks who are on Facebook read your entry, and they conclude that either you have been lying to them or you have the world's fastest healing capability.
And then it's all public.
If you don't want to come to church, that's your call. But lying about it isn't too cool. Just tell the truth, or keep your mouth shut. Because if you lie, folks start wondering what else you've not told the truth about.
Now truly, this is nothing that will send you to hell. But it surely disappoints others, and sets up a situation that can escalate.
It's not logical to expect people to notice when you post pictures of cute kitties and puppies; and then for you to cry "None of their business!" when your words and actions don't mesh and people still notice.
So.....it's easier to tell the truth. Just sayin'
