Having said that, why doesn't this woman go out and get her own taser/spray/firearm/whatever?
Are you her gaurdian angel?
You gonna ask that to every guy who shows concern about any woman? The obvious answer is because I can.
I don't know how you are wired, but when people are around me, I feel responsible for them since they are in my company. That's why I carry. I don't have a problem if my friends don't believe in guns. I don't force that issue on them, nor them on me. All I can do is try to accommodate their needs if such a need arises.
