Infuriating Objects

What everyday objects do you find annoying? The ones that always cause a problem?
1. Sellotape. I always lose the end of it and have to turn the roll around several times, running my nail along it, trying to find that tiny difference in thickness where the Sellotape starts. or is it ends? I actually dread using Sellotape and its big ugly sister, masking tape.

When I need more than one piece I stick the end down on the edge of the table so the roll hangs off the edge, then it's easy to lift with one hand, a finger against the sticky side and the roll in my palm. Of course if you have a large roll or a new roll of packing tape or similar what then frequently happens is the weight of the roll causes it to unroll all the way to the floor
