Hang Ups

I have a hang up about grammar and spelling. I know it's rude to correct people and I bite my tongue a lot, I really do. However. There are some things that I believe any educated adult should know. Sometimes people learn things wrong from childhood and it's just hard to break the habit, such as my problem with the incorrect phrases "might could" and "used to could." I think these are examples of regional dialect and that's not really the issue I'm talking about.
By writing this post, I'm guaranteed to make some sort of grammar or spelling error just because that's the kind of luck I have, but here goes.

• You're = a contraction of you are. Your = possessive.
• A lot is two words. A dog, a cat, a lot. Make note of it.
• Too = also or excess. To = an infinitive.
• It's = a contraction of it is. Its = possessive.
• They're = a contraction of they are. Their = possessive. There = location.
• It's supposedly, not supposably.
• It's agreement, not agreeance.
• Apostrophes show possession, not that an object is plural. It drives me insane to see it on stores. "We sell T-shirt's!" or "Farmers Market: fresh green bean's." The farmer doesn't own the market, but those beans own something, buddy.

I try really hard not to hound people for these things because it just makes you feel bad when you are corrected. I just wish that people would realize that when you are writing or saying something to other people, that takes away so much from your message and lessens your credibility. Plus, except for supposedly and agreement, they are all fourth grade skills.

Little kids have cute ones that they do. These are no longer cute when you reach adulthood.

• Pacific: "Well, you weren't very pacific when you gave us that assignment!"
• Pasketti: "My mom made pasketti and garlic bread last night!"
• Liberry: "Can I go to the liberry? My books are overdue." [related to the raspberry]

That's all I can think of off the top of my head. I hope your not to mad that I said alot of pacific thing's about bad grammar. Its just me trying to make a difference out their. Supposably.
