End of sleepover

Kids awoke at 5 (Freya lost her pillow) but I sent them packing - woke again at 8 :)
After they went (all gone by 13.00 after playing shops) and we went to grandads to see granny (got the big birds out) - then swimming lessons and kfc (it was minging)

Why am I still awake now 12.13.. Such a long day tomoz
