Just want to let you guys know that Issey's video was meant to be shared with my sisters on FB and I didn't expect it to receive so many views. To my new friends and followers, there is actually nothing extraordinary on my FB profile. Nonetheless, thank you for the love! Here is Issey! My flashlight."
