My GF got me into shisha! Maybe if you setup something really flavorful, like AF Grape or SB X on the Beach, she may like to try other stuff. Start with a really flavorful smoke .. then take it from there.
She used to smoke cigarettes and has recently quit. She loved smoking but quit as a preventative health measure. She'll probably love it once I find a flavor she will enjoy. I've already started warming her up to the idea. I'll have to keep my fingers crossed.
What is a good mint mixer? She loves mint but not real fond of fruity stuff. She hates fruity mixed drinks so I'm thinking it might be the same for shisha.
