since recall wants to try to scare you silly, i'll go ahead and explain it to you. but let me tell you this, you should be able to easily figure this out on your own in 10 minutes of pondering upon it.
"Hello, is it possible for a time traveler to meet you and blank out your memory so you don't remember anything?"
"if you are between his agenda, the short answer is YES"
the short answer is no...
the long answer is if they blanked your memory on that, they wouldve blanked the memory of that question out too...
that is, if they werent idiots. in which case, howd they get a memory blanking device being an idiot and all?
