U is for Universe, Mr. and his Love-bot (I *swear* you asked for this, but now I can't find where :o)

Lenore made him happy - simple as that. It was by no means a conventional arrangement, but even if his tastes didn't run as they did, Mr. Universe had no delusions that his lifestyle would appeal to a real woman.

Lenore doted on him at his convenience. She didn't get offended if he ignored her for days while developing some nuanced code or tracking down some obtuse government conspiracy, or both.

Lenore didn't laugh if he got out of his chair for a victory dance, but she did always smile when he came to her for a more intimate celebration.
