Of course for those who are on social media with real name and photos this answer is obvious.
My family knows that I collect cards because often they pick up the envelope out of the mailbox for me. Very few people I know in real life know that I collect Pokemon for safe reason.
My family collects, and my friends also collect. It’s a fun common thing we share and I’m grateful for it. I’m just a little further down the rabbit hole than they are.
My friends and family know I collect and they know a few cards in my collection, but they don’t know the full extent since none of them collect and they wouldn’t fully understand it anyway.
Had a friend jackhammer a safe into concrete. He asked me what it was for so showed him some cards. Turns out he stood in line for 6 hours at the Pokemon Center in London on opening day. We’ve been friends for 5+ years and never knew, glad we do now.
