Accidently got myself into a new hobby

I went out today with my brothers (Older and younger) as well as my grandmother. We were pulling into a burrito place and saw a Warhammer 40k symbol on a door but my older brother and I thought it was part of a gamestop so he said "Imagine if that was a store dedicated to Warhammer" we looked at the sign on top and it was a Warhammer store. We both walked in and my grandmother and little brother were in a crumble cookie. We originally were going to look at the figures there, but we were curious and asked the owner about Warhammer. So now when we each have money we will get a starter pack.
