Once when I was about seven, a babysitter had a friend over who brought the video "Planet of the Apes". Of one or another reason I was allowed to watch it, which made me think there were apes under my bed, apes under the stairs (so they could grab my feet), and apes in closets and behind doors. I`m over the bed-thing now, but I still run the stairs. I`m born in 75.
