I'll cringe, but it's the content of what they say, more than how they say it. A person can be really ignorant when it comes to spelling, but so smart in other areas.
I correct the hell out of them and attempt to get them to use normal typing. SO they get a chance at first. After a while though I'll cut them off if they insist on using the damn internet speak. I can't stand it really and see no reason why such laziness needs to happen rather than type out full words.
LMAO I even type out fully in texts. And I'm only 37 you young whipper snapper. Now git off my lawn!! *shakes fist*
Not at all. That would make me a very small person.
