Infuriating Objects

What everyday objects do you find annoying? The ones that always cause a problem?

I have two in particular,

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.

2. Clothes hangers. They always seem to get caught up with another hanger in the wardrobe and garments fall off onto the floor.

When your finished using the tape always roll a little bit back on itself so you can always find the start. Works for cello tape sello tape, masking tape, packing tape ......

That's OK when you actually "finish" but, when you're in the middle of taping up an envelope, cut a bit off, stick to the envelope, go back for more tape and the end has disappeared. Grrrrr.
