Today I was helping some children in the summer recreation program near my hometown. One child decided to lie to me and say he didn't poke me, when I actually watched him do it. But when he lied and said he didn't poke me I said, "Yes you did, I seen you!"
The child literally laughed at me and told me to go back to Pre-K and learn English. I was so humiliated because I even knew that sounded incorrect! When I finally got home I decided to look up the correct ways to use "seen" and "saw."
One would use "saw" after a subject. For example, I saw the kid poke me. One would only use "seen" when using a helping verb, like "have" and "had." And since I have worked on verbs in my short paper, I knew what a helping verb was. When one would want to use "seen" they could say something like, I have seen you before.
I'll make sure I don't make this similar mistake again because I don't want to be laughed at, especially when I plan on being an English teacher in the future!
