To show I care

I e-mail my sister on a semi-regular basis. She is in Kenya, so e-mails are the only contact I have with her. I like to remind her, at the end of each e-mail, to show her that I care.. So I some how incorporate a message suggesting that she avoids death.
"Avoid getting eaten by lions." is my favorite way to sign off..
So far she hasn't died.. So I'm thinking that she's really listening to what I have to say.
