Aren't they all?

My wife had a problem unclipping, it turns out the her pedals where filthy, which caused the mechanism to not work very well. I hosed them down with WD-40(to clean them, don't get excited), lubed all the pivots, and the worked like almost new. I asked her, did you notice them gettting worse? Of course she started having problems weeks before, but waited till she almost twisted an ankle getting out to tell me.
