I feel like throwing tantrums sometimes too... Pent up energy. Do you have a walkman / earphones? I can't jump around too loudly either 'cause the floor creaks... But I can really stretch my muscles and swing my arms around and stuff... You have been doing lots of sleeping, eh? The body gets cranky with that after a while... Needs to move around... But too much sleep and I just feel sleepy and iritable. You are on holiday at the moment, eh? I find that lack of external structure means I sleep a lot and then feel really depressed and tired and anxious and cranky too...
