home alone

Today is the last day of school. The big one has gone straight out with her friends and is sleeping out. The little one is at a party and doesn't need picking up till 8.30pm. The other half is going to football and the pub.
I am home alone!!! 
For 4 hours!
I can't even begin to decide what to do with my time. Because this never happens. 
I'll probably just dither about for 4 hours and wonder what to do. Or I'll do some work. Or hoover the stairs. Something worthwhile anyway I imagine - to make the most of those 4 hours....
