To suggest DH gets a taxi

[sleepy11]

DH has a minor op on Friday and has to be at hospital for 7am.
I need to be at home for getting kids ready for school so he asked his mother for a lift - this was before we knew the 7am arrival time.
I told her today that as it has to be 7am thay he will get a taxi as I don't think he should expect his mum to get up before 6am to give him a lift. He is now in a huff.
What the hell is wrong with a taxi? He's not ill or anything, it's a cyst removal!
Was I BU to tell her not to worry about the lift?

If it's not too late, and going with the earlier posts that suggested your DH might want the company/support, can you're MIL stay at yours the night before, you take the DH to hospital and she gets the kids up, breakfasted and off to school?

Why did this situation need your input at all? I'd be huffy about it too.
