I did something similar but I wasn't 8, lol...I was tired from my job, & about 10 pm sat down in my recliner chair to watch the late news with a snake on my lap. I dozed
off for about 5 minutes or less (I could tell because I didn't miss much news) but it was long enough for the snake I was holding to slither off my lap & hide under my chair.
I found him right away of course, but I have to wonder how snakes always seem to know the moment your attention strays? And obviously, it's not only me.(I was
quite relieved that my snake was ok, & it occurred to me that he could have been injured in the chair mechanism.)
