It very seldom happens that we don't eat meals together. I can't remember the last time Rob was away or engaged in some activity that spanned a meal time and didn't include me. When it does happen, though, there's very little to get a fix of in his absence, because he likes everything. I just eat normally -- whatever that feels like at the time.
I usually go ahead and make a nice meal (i have to cook a ton of my own food because i have some GI problems- i like to know what goes in my dinner...etc so it won't make me sick
) So i will normally go ahead and make a full meal- and just save some for whenever Colin gets home so that he has a nice dinner waiting for him
