wtf rant

I am sure you are all familiar with acronyms like wtf and lol. Having a teenager I learn a new one daily. I can't lie and say it isn't annoying to me. Are you really saving tons of time using acronyms like this? Let me break down a normal texting conversation that my son has with his friends.

Wdywtta? (what do you want to talk about?)
Idk, wdywtta? (I don't know, what do you want to talk about?)
Idc. (I don't care)
Lmao, we r dum. (Laughing my ass off, we are dumb.)
Lol, I no. (Laughing out loud, I know)

It makes my head want to explode. The only saving grace for me in this is that he is a teenager so I expect it out of him. But today, oh yes, I drove by a church in town with these types of acronyms on their sign. Brilliant huh?

NO MATTER WHO U R
U R WELCOME HERE!

I thought I was going to drive into the side of the church and crash into a big fiery ball due to the bleeding that was occurring inside my brain. I have a problem with the crazy advertising and slogans that churches have started to display outside. Like this one....
"WHEN YOU ARE IN HIM AND HE IS IN YOU GREAT THINGS HAPPEN!" or this one,
" TOUCH EVERYONE FOR JESUS!"
These are bad enough as it is, but you start adding acronyms into the mix and I just want to scream.
