Just tell them something about them reminds you of your parents
Or tell them it's not gonna happen and you are sorry but you are blocking more emails from them.
Actually, we are trying to broaden the age range we are willing to play with...no prob going up 20 yrs but down 20? That's less than 30! But it's not fair if I can go 20 older to not consider 20 younger cuz if a younger couple is going 20 older as their play limit, then WE are saying nope, too young but those older than us are letting us learn and have fun from them.
