text_A: While there was n't too much available for their age ( ball pit , bouncy area and a little padded pyramid to climb on ) , we went right when they opened at 10 am on a winter weekday and ended up being the only ones there , so we were given a little more liberty than we would have if others had been there .
text_B: The opening did not happen
not-entailed.
