This. It's more awkward if it is someone you see all the time. In which case the common thing is to say you aren't on FB all the time.
So you know, it's also possible to "unfollow" and hide posts from a FB friend on your newsfeed and put friends into different categories like co-workers, acquaintances, family and have your post go to something like friends except acquaintances group. I've had to use both when defriending would cause more drama than adjusting settings.
