my dh buys me jello and fruits in cups. I can't get the lid off of them. they are clear plastic, and you have to be 18 with the strength to open it. Very frustrating. oh, and string cheese is a bummer too to gt open. I have one of those plastic mesh things to open jars. Thank goodness my kitty doesn't eat that smelly catfood, or tuna for that matter. she eats Blue Buffalo dry feed.
