my friend is acting wierd...?

[snugglebear20032004]

the other day my best friend witnessed me using the heimlich manouver on her niece.she was amazed at how well it worked,and insisted i teach her how to do it. so i taught her how (no actual thrusts involved).i showed her the abdominal thrusts and explained how it worked.she asked what she could use if someone was obese or pregnant.i showed her the use of how chest thrusts works on such people. she told me that if she ever became a choking victim she wanted me to use chest thrusts on her.i told her because of her slim build the abdominal thrusts would work better on her .but she insists on me using chest thrusts.i asked her about it all she would do is turn red and laugh.my friend is very attractive looking woman and i'm not interested in her as yet. what is going on with that?
please help!!!!!
