Hi Gracek,
I think you will find this is due to the disappointed result on X-Factor The little guy from Asda had no chance, because the song that was chosen for him was fixed to ensure he losses votes. ( according to my son).
Also it could be down to having a little too much tea or coffee with caffeine and of coarse you may have eaten too much of your nice snacks which made your stomach and brain work overtime.
Not happy is not too much of a problem as long as you keep everybody else Happy.
Recommendation For Tonight: buy a Beano comic and read before bedtime.
