Keeping Speaking Skills Sharp Solo

I've noticed my fluency starts to dip if I don't speak for a few days. Since I don't always have a partner, I've started narrating my daily life like a cooking show host! Today, I described every object in my kitchen while making coffee. It feels silly, but it helps maintain my flow. Does anyone else use 'background narration' to keep from getting rusty? I'd love to hear your creative solo drills!
