I just told my DH. He kept going on about my present and I was trying to hide my face. I am comically bad at lying (another reason I was worried about acting surprised). He knew something was up, so I blurted out "I KNOW WHAT YOU GOT ME."
He asked me how and I told him. He then said he was going back and forth on whether or not I'd like it and asked me what I thought.
I told him I really appreciate the thought an effort and that I'd probably like it though I'm not sure where we would put it and it felt more like a household gift.
He said okay, since he was going back and forth on whether I'd like it, we will just keep it (if we can find a home for it and like it) and he'd get me something else. Though we'll probably send it back though. We can't really afford it right now.
There's no way I'd have made it til Christmas without saying that I knew. I'm terrible at lying. At least you always know I'm telling the truth.
