Well, at least for a lot of men. It’s just a generalization, I know. But I’m going to use it anyway to make a point. The point is this: it is wise for a person to anticipate certain irritating habits in his or her spouse. If you are a woman, you may find it maddening that your husband can’t find the ketchup when it’s right in front of him. You may even have suspected him of doing it on purpose sometimes. The fact of the matter is that this really is a common issue with men. It behooves you to expect it, so that it won’t bug you as much when it happens, and to recognize that you’re not the only one who has to deal with it. Ask some of your girlfriends and see. This mindset will go a long way towards making his handicap less irritating.
For men, I might suggest the same approach as regards timeliness – many women are less punctual than their husbands (and yes, I know, it’s certainly not all of them). It is helpful for men to anticipate this and see it as part of the wifely package.
This is not to say that these matters can’t be worked on and improved (my ketchup-locating skills have definitely developed since I got married); just that they ought to be expected for one’s peace of mind and peace of house.
