I have one that is normally locked away and safe near my bed (but only takes a few seconds to open due to fingerprint locks, sometimes technology is really cool). And a bat that I've had since I played softball in high school (IDK why I keep it with the gun but it's like its own little safety net). When I sleep alone I have a knife too, but if I'm at my carer's place he has a shotgun and I tend to stay unarmed there since I don't want to ever hurt him if/when I disociate.
During the day he teases me because as he know it's never a question of if, but always what/ how many/ and where (considering I had to use a metal spoon at one point against a much larger bully in school I could make most things dangerous lol).
Think it has to do with growing up with 2 uncles for Marines, a Navy SEAL for a cousin, and a few others in different military branches they always made sure I knew how to defend myself (I'm 5' and 100lbs it could be/has been easy for some to take advantage of my size). Though looking back it's probably a tad messed up to be teaching a 10 year old military tactics/attacks but that just adds to my list of oddities I suppose.
