history: my neighbor keeps borrowing my shopvac and never returns it on time my neighbor keeps borrowing my shopvac and she never returns it on time You may want to think about not letting her borrow it anymore.  Sounds pretty rude to me.
current: i'm a nice neighbor but this hass been happening too many times now
next: Maybe ask her to set the time when she can return it so you have a better idea when to expect it back.
