too much laundry !
The heavy dried laundry that I collected! I threw it to my bed and actually sometimes I even sleep with them. The day after that, I realised that where the heck is my top ? Then I found it on the bed.. crumpled :S
I am very sure, students who live alone always did this. My housemate does that everytime I go to her room. So, I am not the only one though. If I am at home, I will be nagged shit and flat by my mum! hahah~
