Simple Disagreement

Time management, well as soon as I think I might have it down, I go and add something else.  And guess what suffers, the not so fun things, like washing and folding clothes.  Or cooking everyday, my groom and I had a heated disagreement Tuesday evening.  Well, pretty much he felt I should have cooked, but I cooked the day before which should have lasted for Tuesday.  Anyway, once I got home, I did log on the computer for awhile (problem #1). 
However, my 2nd son, the one who completes assignments ahead of time, needed more supplies from the store. Tuesday is Bible Study, but I went to the store to also get food to cook (had nothing thawed out) and I needed to get gas.  Once I got back home from store, what did I do (problem #2) got back on the computer.  So my handsome groom came to inform me that I should be cooking.  Why did he go there?  As long as he's busy doing what he wants it's okay, but let him find me on the computer it's a problem.  Well of course that's the way I see it, he sees it as me rejecting what he asked.  But in all fairness, I should have cooked first, and then got on the computer.  Over twenty years of marriage, and we still have simple disagreements like this.  Pray for me...Needless to say, I did stay up to midnight to cook dinner for the next two days hopefully.  I apologized.  However really, life is too short to be upset over the simple things.
