Hi, I'm Mikey D and I'm a Star Wars geek
The wife tolerates it and my immediate family knows (most, however, were surprised at how much I had when they came up for my wedding and I showed them. And 95% of it is packed away in a closet. All I did was slide the door open and their jaws dropped). Most of my friends know but don't probably know the extent of it. My co-workers know as I get my on-line orders delivered to work and have a few figures on my desk.
Now, if you saw me walking down the street, would you know I'm a fanatic. Probably not. I only wore the few T-shirts I own to opening nights of TPM and AOTC. Its not that I'm trying to hide my hobby, I really feel Star Wars T-shirts is not appropriate dress apparel. I don't know why I feel that way as I'll tell anyone who asks about my hobby and will be proud to show it off any chance I'll get, by T-shirts is a no no IMO.
Any you know the weird part, I won't wear a T-shirt but I will get a tatoo. Think about that for a minute
