The nighttime thing hasn't changed appreciably. Wednesday night we all slept together, with difficulty. Thursday night Mom slept on the couch. Last night we all tried it again together, but Mom went out to the livingroom at about 2:30 a.m. so Dad could get some sleep (with me sequestered in the livingroom, of course). So nothing's changed.
Oh well, can't blame a guy for trying, right? At least we're all happy and we love each other and nobody's blaming anybody else for this state of affairs.
Hope you're all having a restful weekend! Ciao meow!
