Well, more likely she is "bullet resistant" to a certain degree.
This past weekend we went down to San Diego to visit her brother's family. We got down there in the mid-afternoon and Friday. They already had plans for dinner so we took our boys down Belmont Park to the WaveHouse for dinner. It was pretty cool, they have a wave machine type thing that you can see from pretty much anywhere in this outdoor restaurant. People are able to ride surf boards on this machine generated wave.
Anyway, we came back after dinner and got the boys tucked in, since they were rather tired. Then we went out to the living room to hang out with my wife's brother and his wife. We all were up til about 11 when me and my brother-in-law decided we were too tired to talk, or even listen for that matter, and decided to call it a night.
So, we left my wife and her sister-in-law to talk the evening away.
Now it is important to point out that their living room is on the back of their house and they have a closed in patio off the back of that. Also, the I-8 freeway is almost literally in their backyard. You can see it from their house. The only barriers between the end of their lot and the freeway itself is a chain-link fence and a big concrete drainage ditch.
Well, at about quarter to 1 in the morning my wife and her sister-in-law decide to call it an evening, since our kids would be getting up in a few hours and they should probably get some rest.
As they are standing up they both hear glass shatter, or more likely pop. My wife's sister-in-law feels this sort of shower of glass particles hit her all over her back, and my wife feels something bounce off of her leg.
