The fact that so many people did not realize the the OP misspelled know and right on purpose…boggles my mind!
The beis yaakov in kew gardens happens to be fantastic. They spend a great deal of time teaching math skills, grammar, spelling etc. Lets not generalize.
I agree though texting definitely has had an impact. My friend texted me yesterday saying, ” So in the end where your being for first days?” This is NOT English. Obviously i am not a fool and i can understand what she was asking, but every time she texts me something like this it drives me up a wall!
