DD9 has wanted to do an activity forever, and there is finally a class for her age group that I can get her to. If I have the car and if DH works from home so Ds 11, primary, can come home from school to someone.
DH said fine, he can arrange to work from home that day each week, no problem - I'll have the car and he will be home for DS.
Of course, now it's actually reality, he has said he can't possibly work from home that day and it's ridiculous for me to expect him to arrange his working week around our timetable. Problem being, I now have no one home for DS and potentially no car. We do have alternative transport, a scooter he bought so he wouldn't have to use the train to commute. This was not an issue last year, but apparently expecting him to take the scooter on the couple of days I need the car and he has to go into the office this year is because I want him to die 
If Ds is out on time and if there is no traffic we should be able to drive there with five mins to spare. But it's the first session and we don't know exactly where it is and Dd doesn't want to be late. Would it be totally wrong to ask if DS can miss the last 10 minutes of class (music lesson) this week so we can leave when we'd originally planned to leave?
