down with periods

Hmmmmm, I've never heard of that! That's funny though.I blame the texters.
Heard somewhere that if you put a period on the last sentence in a text it mean you're ticked off. Not a texter here but WTF!?
Punctuation could save a life....I get accidentally leaving a period out when you go to a new perigraph. But at least use commas or something to catch a breath
"Let's eat Grandpa!"
"Let's eat, Grandpa!"
Unless you're dyslexic then it might be 24!I thought the answer to everything was 42
