First off, is it hoarding if it is something that is needed to be successful? From trip to trip we don't know what the hot set up is going to be so we have the ability to change various pieces to make the set up more attractive.
Secondly, I would guess that she has something that she "collects" like purses, shoes, clothes, jewelry, etc. So I ask you sir, is this not also hoarding? Maybe it is she who has the problem. Maybe your lure collection is just your way of coping with her affliction.
Turn the heat back on her to take the spotlight off you. Then go buy some more lures. Just remember...Moderation in everything...including moderation
