When you give birth to apes, it is extremely helpful to have a couch with the cushions firmly attached. As in, sewn into the couch by the manufacturer.
Because your apes will do this 1,246,487 times per day.
Need I mention that this usually always results in one kid both kids falling crying bumping their heads hurting themselves?
We used to leave boxes on couches and chairs if we didn’t want dogs or cats taking residence on the furniture. Perhaps I will have to come up with a similar plan…
