However, do watch out for the follow up that "we agreed", if you do not debate when it affects your life. I like to treat my DGS in the holidays when he comes to me - hubby said " play spaces are getting ridiculously expensive", so next time we went out, his rant was "we AGREED that you would not spend money on play spaces"
