I may well be BU here but I'm genuinely interested in the view of others.
I had provisionally booked a Pilates class for this evening, but for me to go I needed DH to be back by 7pm so I could go.
I texted him this morning to ask if he would be able to get back early so I could go. He didn't call or text back. I didn't call him to ask because I was crazy busy at work. So I assumed as he hadn't called or texted back he couldn't get back on time so I didn't confirm my class.
He arrived back home early so that I could get to class and now is cross that as I hadn't heard back from him I didn't confirm the Pilates class and now I'm not going. I'm cross because I could have gone to Pilates if he had called me. Who is right to be cross?! (Probably neither of us!)
