I had to leave at 7am for work. Dh didn't need to be in until 12. It's half term and I, as seems to be the default, organised childcare in advance for dd1, aged 8 to be taken care of by a friend who has a similar aged daughter. Friend asks if dd1 could bring her bike so they could both have a ride together. I thought this was a good idea and agreed. Dh is now blaming me for his sore back as he said he twisted it wheeling a bike whilst carrying his heavy bag. He got really quite nasty this morning, ie. his tone of voice. I said hd could hv asked dd2 (aged 11) to wheel it on the 20 min walk around to friend's house. Alternatively, if he'd thought it was going to be a problem, he could have asked me to take his bag to work in the car (both work at same business premises). Do you think I'm being unreasonable or is he out of order here, blaming me?
