I personally will save my contributions for those that don't cuss me or act like I owe it to them.
Just like Christmas. My joy is giving a gift to delight the receipient. If I gave (and have) a present to my child and he complained about it not being what he wanted, I'd take it back IMMEDIATELY. He would get NO gift.
Why would I expect any less from an adult? Being through trying times is NO excuse to me.
