sing your own special song
<Snipped quote by TupperWare Bowl>
Chances are, you are not microwave safe.
However, you are convenient for transportation of items of relative unimportance, like potato salad or craft supplies.
You likely don't feel the need to sell yourself too much because people already treat you as a household name, although exceedingly commonplace. Such a household name, in fact, that no one actually gives a damn, and takes you for granted.
Until they microwave the shit out of you and you infect them with disease.
It's possible you often feel limitless, though that may be because your lid gets fucking lost all the damn time and FOR GOD'S SAKE KAREN WHEN YOU PUT THE DISHES AWAY MAKE SURE THE LIDS ARE IN THE SAME PLACE AS THE CONTAINERS I SWEAR WE'VE GONE OVER THIS BEFORE.
