BEST way to convince my mom im sick?!

barf on her lap?

I KNOW you wouldn't fake being sick instead of going to school. What could possibly be nicer then being at school with your friends instead of staying home loafing? My mom always told me you should never pretend you are sick because if you do, you really will get sick and it won't be fun. This is the advice from someone who knows. Once you start lying about being sick, if your parents know you are lying, when you really do get sick they won't believe you and you will wish you had never lied to them. If they do, in fact, actually believe you, and they discover you have been lying to them (and they will find out eventually) they will feel like you have betrayed their trust in you and you have used them and they can no longer trust you. It isn't worth it. Not only that but if you continue to lie if you get into any kind of serious trouble they won't be there to support you because they will assume you do nothing but lie so why should we try to help and protect him. It is just another lie to get or let him do what he wants. There will be some major trust issues later on at a time you might need them the most. It is much easier to tell them truth, then you don't have to try to remember the lie you told them and get your story mixed up.

Brandon...are you serious? lol that is ridiculous. Parents know when you are faking it (unless they are not interested) Go to school!

If you've been ill before with a virus or bug repeat those symptoms; it will seem less like you are faking. If you've been to see someone who had a cold or something replicate those symptoms so it seems as though you caught it from them.
Don't Do Something You Want To. Your act will be a whole lot more believable if you miss something you really want to do, whether its leaving half of your favorite meal or canceling going out with friends. Your parents will believe you more if you sacrifice something you like to do as well as the thing you don't like (school)
Stomach problems. Only eat bits and pieces of dinner; when your parent(s) ask what's wrong, tell them that your stomach hurts. Make sure you hide snacks in your room so you can miss a meal so they think you are sick because you're "not feeling well." If you normally do your homework, get started on it, but put your head down periodically so that they see you're not feeling well and it's interfering with your work.
Sore throat. This only works if your parents are not the over-worrying kind. If you have over-protective parents that go running to the emergency room over a minor strep throat, do not attempt. The day before you plan to fake a sore throat, say that you're feeling a bit scratchy in your throat, and clear your throat a lot. That night, at about 7:45pm/8:00pm, say that you feel tired, and that you have a headache.
Cold/flu. Breathe only through your mouth, as if your nose is stuffed. Then make sure you say a lot of "mmm's" when you are near your parents. If you're not in the same room as they, and they ask you something, hold your nose slightly when you talk. Wear many layers of clothing. This makes it look as though you are freezing, since sick people feel cold easily. Sneeze loudly, then sniffle in front of your parents. Do this also when they're not in the same room but can overhear you from wherever they are. While they're not looking, rub your forehead, face, and eyes (if you have parents who check your face for temperature) then approach them, saying you don't feel so great. It'll make your face red and warm or take a blow dryer and heat your face and say your feeling warm.
