People using incorrect grammar, and spelling.
for example.
WHY do people do this? Instead of saying
"Would you like to go to the park this weekend?"
they instead say
"Would you like to go park this weekend?"
OMG it's so annoying.
I would rant about that a clinic at school only offer ice, band aid, and bed..that's why I never go to school clinic because if you have headache, tummy ache, or whatsoever they'll just give you a freaking ice..
