No sarcasm here at all....

Hi kids.

Thought I would type this letter as it's probably easier to read.
Firstly thank you for stopping to read this, maybe you haven't actually even stopped to read it. I'm sorry I've interrupted your time as I know you are both very busy people with all that you do.
I really just wanted to say how much I appreciate you for letting me do so much for you.
I loved getting up at 6.30 yesterday morning to make your lunches for school / college. Because I've seen how very busy you are having to watch YouTube whilst trying to struggle to eat breakfast, if you'd like me to maybe next time make your breakfast as well please let me know it's not a problem. I see how long it takes to straighten your hair and put your make up on, I should really spend more time doing mine but you see that would involve me doing less for you which we don't want. Please don't thank me either because it's really my pleasure.

You were both very ingenious watching me hoover your bedrooms and the whole house yesterday. It's my way of showing not how it's done but really that I like to be watched - just to make sure I'm doing it right.
It was a shame to hoover up your finger nails Owen because they looked so pretty on the floor. Charlotte yes you did offer and actually hoover one half of your bedroom to which I'm very sorry you had to do that as I know you're very busy.

It was really nice to wash the floor to then have it walked over by you Owen with your school shoes on as you were clearly demonstrating that I had missed bits, so thank you for showing me that.

Thank you also for letting me do all your washing, the joy I get from smelling clothes thrown on the floor makes my day, if you want to do it more often it's no problem I clearly have the time to do it and you don't. 
I really do love spending the majority of the day willing it to be home time so I can come home and bake you nice things, get the washing in from outside that I hung out in the morning because I know how busy you are. I love having to think of lots of different meals that I can cook for you. It makes my night when we are sat around the table and you leave most of what I've put on there, because you are showing me I must make better food and think harder about what I'm making.

I'm sorry that I have to go to Sydney for 5 days with work as I won't be able to do anything for you but don't you worry Saturday evening I'll be back and already I'm looking forward to doing it all.
Don't you worry about dad either having to work 12 / 14 hour days after all its our pleasure. As long as you get everything you ask for and everything done for you. We really don't mind.

Thank you kids for letting us do so much for you.
