Practice on yourself to see if it is real.

You imagine that your the lowest skill possible for this and that you want to give this "Magic" a fair try since you were kind of excited so to be on the safe side and not risk deleting any important memories you decide to write a name down on a pice of paper and fold it in half. The idea is that if you are able to remove knowledge of that name from your mind then look at the paper and not remember writing it then it would be fair to assume it worked otherwise you would be crazy. You spend 20 minutes mimicking the instructions perfectly yet you can still remember it clear as day after an hour of making stupid looking gang signs you start to feel your mind become fuzzy and the memory of the name fade away and you cant remember what you wrote on that piece of paper. Even when you read it you can understand it but have never seen it before but you know you should have. Imagining the power that this could be you decide to quickly sneak off to the library to find the address of your coworker so that you could remove yesterdays incident from her mind.

You pull up to her house and star to have a look around and notice a bedroom window open so you decide to go and have a look, to your luck and amazement this was the right room and she is sleeping. you sit there for 20 minuets making finger signs trying to get it to work and not knowing if it even had worked until all of a sudden you feel a massive drain on you and pass out. you wake up later just as the sun is coming up and thankfully you still haven't been discovered so you quickly head home with a massive headache and praying that it had work as you had work that day. When you get home you slip back into bed and fall asleep imminently.
