DP and I live together and share cooking. Tonight was one of DP's normal nights to cook dinner.
I found out this morning, literally just as I was about to leave the house, that the three-day 100-mile-each-way work trip I was departing for was now just the one day so I would unexpectedly be back home this evening. I told DP this immediately.
Got home (three hours later than a normal office day) to find that DP had made and eaten her own dinner, but had left me to fend for myself and could not even offer a reason why. I have made my displeasure at this situation clear and DP has gone to bed in a huff.
