This is why I text and email my husband rather than call him during the day. I told him the other day, "Whenever you say 'I told you about XYZ, right?', assume you haven't. Every time you say that, it's the first time I'm hearing about it." He just has so many things going on that he can't remember every conversation. For my part, I remind him of stuff constantly -- but gently, in advance.
Ooh! I like that. Of course, Hubby can't receive texts where he works (basement). But I've told him: 1) Check on his way out of the building; 2) If it were really important, I'd call, so the text is merely information
