Contexts are not only places available, but tools available.
Example:
Computer
Internet
Those are two contexts that use the same tool, but one context could be used only where you have a computer and an internet connection, primarily the internet connection. The other context can only be used when you have a computer.

Gifts begins to seem outside context, unless it is around Christmas time and you want to see all the gifts you need to get for different people. Personally, I have a different program for lists like gifts.
