Bad grammar!

I was a grammar freak before this pregnancy but I swear, reading some of these posts really gets to me.  I worry for the future.  Most smart phones have spell check.  Why don't people use it??  Or at least check their post before posting?  I guess people don't think it's a reflection of themselves as a person, but it certainly is to me!  I'm an educator, and despite the fact that I teach math, I am consistently correcting my students.  If I don't, I'm doing them a disservice!
