# Completing a Metric Space, Intuitively

/An incomplete metric space is very much like a golf course: it has a lot of missing points! (A golf course has exactly eighteen "missing points" a.k.a. holes.) The process of completeting a metric space is akin to filling the

*holes*( = limits of Cauchy sequences) in a*golf course*( = the metric space) with*dirt*( = equivalence classes of Cauchy sequences).
