Clothes and Me

I am a 32 year old young and handsome man ,Yesterday ,I went inside the room and decided to change my clothes ,I felt a girl in the next house looking at me so I decided to close the window and gone near to the window she is smiling  at me  and look glance at me so I remove my shirts and trousers without closing the window now I am with my underwear still she is looking at me anxiously so I am confused ,

can any one tell how I change my clothes............?     

I will write next day
