Homework Statement
OK, just a short question about a lemma I'm going through in Munkres and a part of its proof.
I won't quote the whole lemma (it's a few statements which are equivalent), but only the part I don't get:
Let X be regular. If every open covering of X has a refinement that is an open covering of X and locally finite, then every open covering of X has a refinement that is an open covering of X and countably locally finite.
In the proof it states that this is trivial, so I'm missing something obvious apparently. But I just can't see what.
Thanks in advance...
