Why can't mascara stay put? If I wanted black smudged marks under my eyes I'd rub eyeshadow or eyeliner around. But no! Is it really too much to ask of a mascara to stay on my eyelashes more the half an hour? My latest fail is Benefit Bad Gal. My lashes are quite long but fair and I'd like them to look thicker. Is it too much to ask? I find No7 just add colour but nothing else, not keen on maxfactor, clarins wander off very quickly and Clinique stick my lashes together so I ended looking like I've only got three lashes
