Mom, can I borrow the keys?

Mordechai came home and announced that Binyomin wanted him to come over to his house after school the next day. He dug in his pocket and fished out a paper. Unfolding the paper, he continued to explain that he had taken down Binyomin's phone number and address (with the exception of a backwards seven, the info was accurate). So, could I please call his mother to finalize the plans? Sure, whatever you say, cap'n.
