I am a single parent to a 9yr old and a almost 3yr old. My ex left me with a monumental amount of debt and since Jan I have been doing an extra evening shift once a week every week, which makes a huge difference.
My best friend (and neighbour)'s eldest daughter has been babysitting for me since I started - she is 18.
She has taken a gap year and has been working in M+S. She warned me that after xmas they may be changing her shifts to a later one, and she may not be able to continue. Fine I thought this gives me time to find an alternative.
Today, she texts me, saying she can't do Thur THIS WEEK, as she is doing a late shift at M+S and cant get out of it...sorry 
Its a bit bloody late notice! I can probably get out of doing the shift but I really need the money especially now coming up to xmas. I can try and find someone else, but am pretty hacked off, and thinking she should honour her commitment to me or SHE shoudl find someone to do it for??
