Example: Can you hand me those papers on the table to your right?
What about using both in the same sentence?
Example: If you're looking for your wallet you left it in your coat.
It angers me that people still don't know the fucking difference between the two. I guess this is just one of my online pet peeves, but it's just annoying to me. Just like I hate 'leet' speak. I do, however, use 'lol' and such online. Hypocrite? No. I just choose to type in a manner in which it's not difficult to read.
