Sometimes I think our MLC'rs fail to realize anyone else's feelings (yours or s13's) ..... maybe its the 'in' with this possible op, "Oh you played chess once, well my s plays" kinda thing. Personall I would have an issue with it ... even more so if dude was offering to buy his way in with the bat deal. My son too plays pony ball, and yeah I am all for him getting better, but I am with you on this one, sounds like a good time to restate the boundary ....then again sounds like your W will do as she wants regardless so this may just push her into it ya know?? ... I guess you just need to trust your gutand pick your spots.
