BEFORE YOU ANSWER THIS SILLY LITTLE GIRLS QUESTION MAYBE YOU SHOULD READ HER REPLY TO ME WHERE I ASKED HER WHY SHE CHEATED:
Message: Do you really think i do not check who gives me the wrong answers. I know because when 30 or so people give the same answer and show their work. I know the answer is right because i look at their work step by step and see what makes more sense. So far i have been getting 100% on my take home quiz. As long as i pass i don't give a ****. In case you come from planet Mars..let me officially welcome you to earth, where most people who are sitting on top of the world cheat. Most successes are not honest. On earth my dear especially this day and age even the leaders of the world lie and cheat. what do you expect me to do? I will keep on doing it for that grade A.

Note: i also cheat on exams because the guy who sits next to me gives me answers. So far my average is 98%. Keep up with your honesty in everything you do and see how far it takes you.

3 nearly broke guys decided to share a hotel room. the sign outside the hotel said rooms for $30. They went inside and each paid $10 to the clerk. When the night clerk came on duty he realized the room was overcharged, because of a $25 special. The night clerk sent the bellboy up to their room with five $1 bills. The bellboy not being too smart did not know how to divide $5 among the three men. so he put $2 in his pocket and gave the three men the $3 to divide among themselves. This made each man paying $9 each. If $9 times 3 men = $27 plus the $2 the bell boy kept equalling $29, where did the other $1 go?

We always "put in our two cents"... but we're only offered a "penny for your thoughts"? So... Where's the extra penny?
