Leaving soon....trip almost planned.

I´ll be away for 8 days from Saturday on. I dont know how long ago was the last time I have left Berlin for more than 4-5 days.
I have my flight ticket to Rimini, I´ll be landing in the afternoon and my sister will be waiting for me. It´s more than a year ago since last time she came and pick me up at the airport, so it will be very, very nice. At least I wont struggle with trains, buses and so on.
On Monday and Tuesday I´ll be in Siena. I have booked my hotel, in the very centre of the city. I´ll write some emails, maybe on Monday night I can have dinner with some friends, though I am not very sure I am very in the mood to see the people I have left there.
My sister will come and pick me up on Tuesday. Then I´ll be at my parents place - or at my sister´s one, depending on how long will I stand staying at my parents - until Saturday or even Sunday.
I´ll relax, I´ll eat a lot, I´ll go shopping.
But I really dont want to see anybody else than my family and my grandparents. But I guess I´ll be forced to leave my parents house and go somewhere. Or maybe I could try to look as bad as possible, so my mum wont ever allow me to leave the house....mmmmmmmmmmh I should think about that, maybe it´s not that bad idea....
