history: giving my friend the key to my home my friend has been recently homeless and i gave him a key to my house to come and go as he pleases. 
current: Thats nice of you. It means he can get back on his feet.
next: thats why i gave it to him. he dosnt want to be a bother.even tho i told him he isnt .so i gave it to him and told him to come and go as needed.
