Don't you just hate it when the little tabs on the milk bottle seal break off before you can tear the wretched thing off? I am sure packaging nowadays is designed to make it as hard as possible to get into the product.
Oh I feel your pain! I find the vacuum packed meats the same. You are supposed to pull the plastic tab on one corner and it miraculously peels open.....well, maybe it does if you don't have arthritic fingers like me!
