vacillate etymology
1590s, “to sway unsteadily,” from L. vacillatum, from vacillare (see vacillation ). Meaning “to waver between two opinions or courses” is recorded from 1620s. Related: Vacillated ; vacillates ; vacillating.
A word, in my opinion, that rivals it’s synonyms in complexity with a simple meaning. In other words, a fancy way of stating something ordinary.

For me it is often dinner out, there are so many great options, it’s hard to decide on one.
