Don't know when you should say/write "I" and when you should say/write "me" in a sentence? Read on.
Here's the way to avoid making mistakes with I/me usage: You can always check yourself (and thus not ungrammatically wreck yourself) by splitting up the people in the sentence.
Examples:
"My dad and me are going to the store." You can tell that this is wrong if you split up the people in the sentence.
"My dad is going to the store." No problem.
"Me am going to the store." (?!?!) No way.
The same goes for other similar situations:
"Her and I [or "Me and him" or "John and me"] went to the store." Either is wrong, and you can see why if you split up the people. You'd never say "Her went to the store" or "Me went to the store" or "Him went to the store," so you shouldn't say those things together.
Split the people up and you won't make those mistakes, though you might still wonder why so many people go to the store in my examples. It's because I'm not very creative and I don't find grammar interesting. You don't have to like basic grammar. You just have to know it . . . unless you plan a career as a mime, a cage fighter, and/or a ninja assassin. (By the way, the one professional cage fighter I know speaks and writes well, so he probably doesn't make this type of mistake even while beating someone to a pulp.)
