It's the opposite for me. I couldn't hide my interest from my family, especially considering I used to watch much of my anime in the living room in front of the television. That is, until I received my own for my 14th birthday.
- With the exception of my family and close friends, none of my co-workers know anything about my interest, nor any of the lengthly amount of acquaintances I speak to from time to time. I was like this at school and university too, very discreet. Only a select few (one or two people) would know of my obsession. I wasn't really trying to hide it or anything, I just didn't really mingle within a "social circle" that would have people who would like it. Would you say you're slightly embarrassed by your hobby, hence keeping it a secret from your family?
I mostly watch anime and read manga alone. It's a rarity to watch with someone else or in a group.
I laugh at you.
Go to bed, Vin-kin.
