During a day of study I found myself becoming hungry around 11am. Too lazy to make a sandwich I checked out the cupboard and decide a can of spaghetti would not do (as it had no ring pull) though decided a can of tuna would be better (also with no ring pull). As I started to open the can with an ordinary can opener remembered we had an automatic one. Placed it on and away it whirred for about half a second and then it stopped. I didn't have time for its shananagians so I left it be. Almost a second after the can had been pierced I had the cat circling me, still no time, back to the computer I had to go. Eventually (about 5 minutes later) I was starving and thought I would try some things. After a few minutes of pulling, pushing, lifting and everything I could think of I got it open about 2.5 cms round. All that did was make the cat circle me more. I tipped out all the brine and feed it to the cat (great for a cat who has PH issues and needs medicated food). That got her off my back long enough for me to push, pull and give up all over again. I returned to this about twenty times throughout the day with a minute here and a minute there. In the end I let it get covered in ants (well two but I wasn't about to eat it even if I could) and left it for my husband to rescue the can opener. Well he couldn't get it off and it all went in the bin. Needless to say I was pretty hungry by dinner time.
