Why would you be worried? You don't have a "little women" (wifey) at home, waiting to catch you bringing home expensive hobby stuff.
True, I have my grandmother who hates it when I bring even a pack of FVM wheelsets home. home. She doesn't realize that model railroaders are naturally "disorganized", making use of "organized chaos".
Cost isn't the problem (sometimes it is) its mostly because I "spread out too much".
I don't leave the house except for train related things, or have any friends that are into "hanging out" since my friends are the guy in the N-Trak club.
I guess spending money is my vice...
