Having manners

I just started a Bunko group for some girls in my ward. Now, you would think that since I picked adults, that they would be considerate and have manners and return phone calls and the like. No. It's crazy! Whatever happened to saying you'll do something and then...I dunno...DOING it??? It's driving me crazy! Don't say "that sounds like fun, oh yeah, I'll be there" and then bail out because you had a bad hair day or you have a hangnail or you feel fat. Bunko isn't like Scrabble where you can play with whoever is there. I'm so pissy about this. Deep breath, deep breath.
