to me i guess its the sort of say ur gonna hav an wot uve been up to - for example if uve got an exam on the day u basically think - sh it (okay i gave exam as an example cos im gonna have exams soon - but u get the jist of wot im sayin)
but then theres also an arguement to say that it depends on the type of night uve had - some say that after sex they feel good in the moring while others say they feel tired - and then theres some that say its the type of bed u sleep on
i guess its jus up to u basically - co sme if ive got an exam during the day - im like arghhhhhhhhh
but if ive had a sleepless night im also like arghhhh in the morning - apart from that - i dont know!
soz bout ramblin on - thats jus me!
