1. "Its" should be "it's" because what the writer means is "it is."
2. "Your's" is never correct. It is "yours."
3. "Pickes" is not spelled correctly. It should be spelled "picks."
4. "Theives" is spelled incorrectly. It should be spelled "thieves."
As a graduate of the Harding English program, I hope that these mistakes have been noticed by others, especially those in the English department.
