NAH, except your wife is borderline TA because who doesn't like pizza? Maybe have another conversation, but reframe it more positively. Why does this bother your wife/why does she feel left out? Do you guys get to do things as a family often? Would she like to create a similar bond with your son but maybe doesn't know how? What would make her feel more included overall, without you giving up your special nights? I think specific parent/child bonding activities are nice once in awhile, like you're doing, but you do need to figure out what about it upsets your wife and find solutions to make her feel included in family time as well or you will be TA.
