<human>: Condense the text into a few key points

Within the past year, my mother has started stockpiling food and water more than usual. She's always done it, but now it's getting hardcore. As of February, she has access to some kind of bunker that she says she can "probably" get me into, but the rest of the family is iffy (my three sisters, their families, my boyfriend...). She claims it has nothing to do with the Mayan shenanigans.

She's also saying she's going to have me get some kind of radio license thing this summer. She keeps a book about "TEOTWAWKI" in her purse (and she thinks that acronym is so dang clever). Recently, she's been bringing it up at family events and trying to get others on board. Mostly, people have just been laughing at her. I don't know what to think. Frankly, it's kind of scaring me.
<bot>: My mother thinks the world as we know it will end relatively soon. Is anyone in a similar circumstance? How should I be reacting to this?
