where has my mind gone?

I'm not sure what my problem is I keep having brain farts as the very nice police officer said. First I got my very first speeding ticket while driving to Oregon at least the cop was nice and tried to make me feel better by telling me I just had a brain fart and it happens and then said how cute Ashlynn was since she was waiving and smiling at him and then gave Holden stickers to top it all off it was terrible. Then last night I lost my keys, Billy handed them to me and I just don't remember what I did with them after that I just had a complete brain fart it's just gone not in my memory what in the world could I have done with them while riding in the car from a restaurant to walmart, maybe aliens took them and wiped my memory. And worst of all Billy tells me things and I have no recollection of the whole conversation. What ever fruit or vegetable or vitamin helps with brain function I need it, this sucks.
