While home for Christmas vacation (my sister and I are both in college) I was used to my college routine, so I went to bed somewhere around 1 am or so. My sister, on the other hand, would go over to her girlfriend's house and they would have a bottle of wine, talk about men, whatever it is that college grad women do.
Anyway, she would come home at all hours of the night and generally I would hear her open the storm door...then a pause while she found her keys, then the door open. I got pretty used to it.
One night about 4 am I heard the storm door open and then the security door fly open. I figured I had left it unlocked but thought I had already heard sis come home. So, I grabbed my trusty handgun and my Surefire E2E and went to my door. I had my light in my left hand and my pistol in hand at the small of my back. I peered around the corner and saw someone walking around. I lit them up with Surefire fury at about waist level as to not blind them if it were a family member. Sure enough it was my sister home from her friend's house. I went in the kitchen, laid my light and gun on the counter and proceeded to make her spaghetti at her request. She must have had a good time.
Growing up with a brother and father who are gun guru's and very protective, she didn't bat an eye that I came in arms. She won't admit it, but I think she's flattered. Haha.
