I just read your pet peeve post. I have two suggestions for you:
1. Move yoru garbage can to a different location everyday so that they have to look around for it. Maybe they will get the point. If not, it will at leasst mess with them a bit
2. Clinique Lash Power Mascara, long wearing formula. By far the best mascara ever! It doesn't smudge, run or smear. I even wore it to a funeral where I did some pretty serious crying and it still stayed put. $20 well spent!
