Unfortunately, I cannot compute the average distance between seven sleepy rectangles and one jealous teaspoon because the entities mentioned are not real physical objects with defined positions and distances. Rectangles and teaspoons do not have inherent properties of being "sleepy" or "jealous." This request does not represent a meaningful mathematical problem that can be solved. Without concrete, quantifiable information about the locations and properties of the objects involved, there is no way to calculate an average distance between them.
