How do I give myself a deeper “fate line”?

I’m really close to closing the deal with this one girl but she believes in palm reading stuff and has expressed concerns about guys in her past who have had faint fate lines. I only have hand one date with her and when she asked to read my palms I said I don’t “show hands on the first date.” Well that joke will only work once and next time I see her she’s gonna want to see my hands.

Anyone know anything short of getting a tattoo that will make my fate line more define? If I don’t capture this one (body is REDICK), I will die a conflicted incomplete man. I’ll get the tattoo if nothing else, but Im wondering if I could make a fist all day or tape my hand to increase the crease.
