synonyms:

impromptu, spontaneous, unscripted, ad lib, extemporary, extemporaneous

So, extempore means spontaneous. Like, when we spontaneously went and bought a pizza for dinner because I didn’t feel like cooking. That’s probably about as spontaneous we get around here.

I’m trying to think of something else we’ve done spontaneously.

I know! We bought a mattress spontaneously — after we realized there was no other reason on earth why our backs were hurting that much. Spontaneity emerged after all other possible solutions were removed. That’s my kind of spontaneity.

And you know what? Our backs don’t hurt nearly as much.

So let’s hear it for “Extempore,” especially after you’ve given it a lot of thought.
