Progress Report #1: Zip & Lift

I'm just thinking... Why do we get these "easy-zip", "instant-rip", "re-sealable" food packages now where we can't find the notch to begin our ripping? And why are these re-sealable bags so hard to re-seal? (Press the two ribs together on one end and swipe across for the best way to be left with a yawning opening.) Why all the newest convenience technology if I have to put that thing in a plastic bag, anyway? Why have a pull-off lid on a can of condensed milk? If you're not extremely careful during the last stage of "pulling" - the lids snaps off and cuts your finger. The good news is, the wound will dry quickly under a mess of sticky condensed milk. Why is progress sometimes such a pain in the kitchen?
