Yeah, but DIL isn't there 100% of the time I bet. So, W can't know what goes on all the time at Che Gardener. Point is (and I know you get this) what W's perception is. You don't lie to her of course, but you cannot control what she thinks. May not make any difference, but it can't hurt either if maybe something stokes a little concern/jealousy in her.
I will check out your yesterday post and let you know. Need more coffee.
