Having just realised that I had a rare half an hour to myself, I thought I would paint my nails. I have various nail polishes ranging from cheap as chips to fairly decent - some quite new (less than 3 months old). Ended up throwing most of them away for being too cloggy/dried out/inconsistent in texture. I thought nothing of this until I realised that I expect to throw nail varnish away half used. I can't think of any other product that I buy where I would not expect to be able to use it all up. 
AIBU to think the makeup companies should have devised a nail polish that you actually get to finish by now?
