Lots of nice comments here.

If I may add, when your peers (or managers) take some time off and hand over work to you, write a hand-over document. Always. It's crucial for smooth handovers.

- Task to handover

- Description

- Actions at stake

- Target / Desired Outcome

- Timelines

If you missed an action / task that isn't in that document, then it's really not your fault.
