I know it's odd but I've been wondering if we can use adverbs of frequency with other expressions like once a week or twice a month. Examples:
I often go swimming twice a month.
I hardly ever go shopping every day.
what about these situations:
I take a shower every day
oh, really. I hardly ever take a shower every day ( I want to say that there are conditions that I take a shower every day but It hardly ever happens)
