need you help with these two sentences below:
1 The outer door doesn't lock, somebody could've walked in at any point
2 The outer door doesn't lock, somebody could walk in at any point
besides, what does it mean by "at any point " ?
thank you in advanced
Inthe first, the situation is no longer true- no one can walk in now. In the second, they still could.'At any point' means 'at any time'.
