Its good that they are relaxed but we are soo paranoid at home when we share a bed, my bed is REALLY creaky and P's house is a bungalow that never sleeps and our room is closest to the living area and beside the bathroom, the head of our bed is on the same wall as the head of his Mum's! So nothing naughty ever happens! (well there was this one time in my house when we had too much to drink.... ) But its nice after a tough family day to be able to snuggle up beside each other.
I can imagine your Dad in stripey PJ's with a flashlight pacing outside your room!
I have 3 brothers and 2 sisters and the boys definitely have way more freedom. I am the eldest and I was pretty quiet (I know, the irony, I talk soo much now!)when I was a teenager so my parents didn't need to keep a tight rein on me, they always let me know what they expected my boundaries to be and it worked out, for me anyway. And because I was so "good" the others got an easy ride!
I will bring you lots of hobnobs to the fall sprawl, this sounds like a plan. Failing the fall sprawl I will drop in on my world trip!!
