lol I do it with either hand I really don't think about it.
whatever hand the lighter's in, she's the one sparking it.
I think I actually was ambidextrius when I was younger, but my mom made me chose a hand to write with b/c I would sit at a table and draw well with both hands and she thought that was weird I guess.

and I think we light the side of the bowl with that hand b/c, for me at least, the flame gets a tad too close to my hand and starts to burnnn.
so that way your hand is out of the fire's way.
