If not routinely, have you ever, even once? Watching The Crown the Queen is caught on camera lobbing stuff in anger at Prince Phillip, and when she apologises to the cameramen she excuses it by saying she's sure it happens in every marriage! Does it? I never have but then I've never had a humdinger row anyway. If you throw stuff do you take a split-second to rationally decide what to chuck 'The washing-up sponge is ok, but not the saucepan' or do you just hurl whatever is to hand without even thinking about it? Do you regret it after?
