If your wife suggests going for a walk after dinner for some ‘together time’, and to get in some exercise, and you agree… well, that is considered super-supportive, and she will appreciate you for taking the time. I can certainly recommend that.
If your wife proceeds to walk at breakneck speed in order to avoid crazy-scary, West Nile mosquitoes, and you manage to keep up with her short little legs, she should be verbally commended for keeping your heartrate up, while protecting you from a dread disease. That is considered encouraging, and I can completely get behind that.
If she does not want to carry the water bottle, but still wants to drink from it, you should definitely just smile and hand it over at every 5 minute interval, when she is parched from the insane power-walking session. That is considered helpful, and she will be forever grateful that you are concerned about her level of hydration. I would call that a ‘go-to plan’.
And if after mentioning that even though she knows INTELLECTUALY that the bats swooping around under the streetlights are HELPFUL to the environment, that she is still secretly creeped out just a little?
Well, I do NOT recommend immediately flapping your hand in the hair on the back of her head. That is considered infantile, and she will probably scream loudly and you will end up having to jog after her as she runs home in the dark.
I just thought you should know.
