my friend and I are due to go to the take that concert on Monday. She has a very small baby who is exclusively breastfed and doesn't take a bottle, so the plan was that her dh and the baby would come with us and wait in the car, so that she could feed just before we go in. I was fine with that. Now today friend's dh phones me - as a surprise for her birthday, which is tomorrow, he will take her for a day's shopping on Monday before the concert. As it wouldn't make sense driving wise to come back to their home between shopping and the concert, could I just meet them at the arena please? The arena is nearly an hour away from where we live. I had thought we would go up together. Now I will have to travel on my own. Aibu to think this is quite inconsiderate?
