Crumbs , stalpes , tacks , leggo , nails , cheerios , Brio , chalk or anything left on the floor which would make walking a horrible experience for my feet.....also I hate doorways , treebranches , hanging ornaments/planters , eavestoughs windchimes, christmas lights/icicles , extention cords to block heaters on sidestreets or anything hanging so low it makes walking upright complicated .
