Packing

Tonight I am travelling to Worcester to stay with Tim (who is cooking me something exciting apparently). I am currently trying to get everything into my suitcase. Why is it there is NEVER a suitcase that is JUST the right size?? It's small, compact and perfect, only it doesn't hold all the clothes/shoes/ books I want to take with me - even when it is expanded. I'm only going home for 4 nights I don't need a bigger suitcase- it looks unreasonable, AND i'll have to lugg it back on the train...but things don't quite fit into this one. I don't know what to do, and to make matters worse, because i'm dumb and have no foresight, I only washed my clothes yesterday, forgot to hang them up, so half of what i've packed is really damp... I'm hoping the plastic bag they're packed in will protect my slippers and pyjamas which I will need later...I wonder if Tim has a spindryer!
