[Grammar] I threw away most of my old books when I moved house.

[Son Ho]

Hi, everyone.
Could you tell me the real meaning of the following sentence? Does it mean that threw away goes first or moved house goes first or threw away is in progress during moved house (a period of time)?

1. I threw away most of my old books when I moved house.

 

[tedmc]

Both actions happened around the same time, not necessarily simultaneously.

 

[emsr2d2]

It is most likely that throwing away the books was part of the longer process of packing everything up to move house.
