How to Tell if Someone is Lying

This is for all you people out there who want to know if someone is lying or not.
This is the trick I use to figure out if my brother is lying. I figured this out a long time ago, maybe when I was 4 or 5.
Rebecca's Homemade Solution to Tell If Someone is Lying:
1. If you hear someone say/do something that doesn't sound quite right, look at them ASAP.
2. As you look at them, notice their face. If they have a big grin on their face, or are nervously giggling, move on to the step.
3. Now continue to study their face. Do this in a way that will make them feel uncomfortable, but this will only work if they truly are lying.
4. If thier eyebrows are raised higher than normal, you can pretty much guarranted that they are lying.
5. Okay, all in all, if they have a big grin/smile and/or is nervously giggling, AND their eyebrows are raised, then they are lying.

How to Deal With an Annoying Liar Like My Little Brother:
If you know someone who obiviously lies all the time or you tryed my trick or another trick on them and they seem like they are lying, this is how you have to deal with them:
If they start on one of their constant lies, stop them mid sentence. Say:
"Dude, it's pretty obivious that you are lying. You might as well zip it."
Or something like that. Trust me, my brother lies a lot just to irritate me and no matter what I or one of my parents do, he will not stop.

No offense to my crazy, lovable, little brother, but he loves to annoy me to just my attention.

Anyways, best wishes with this and I hope it works and that it helps a lot. Feel free to comment and say any other ideas you have, if it worked or not, and what you think of this post or blog!

Thanks!
