I'm sorry that the weather is bad.
I'm sorry that we are in an economic crisis.
I'm sorry the Sky box doesn't work and I haven't phoned the engineer yet.
I'm sorry that people are being arseholes towards me and are ignoring texts and phone calls but are happy to use my house as a creche.
I'm sorry I have tried to be a nice person and phoned to see how you are.
I'm sorry I barely talk to anyone now for fear of being kicked in the teeth.
I'm sorry my child passed and yours didn't.
My fault entirely.
