- Putting anything with metal into the microwave
I found myself incredibly reluctant to stow the bag of crisps in the known ant-free microwave last night because of this.
So I put them in the stove.
This, even knowing that I would not turn the microwave on with current contents.
It's just a taboo that strongly ingrained.
Unless, of course, it's a burned CD that failed. Then it is okay.
