What is the greatest gift someone could give you?

This is absolute nerd/Virgo/turbonerd behavior, but I like gifts I could use. Useful (subjective) gifts, like appliances. No lie, one of the most favorite things I ever received was an electric kettle-- gifter just had to right the wrong of my heating up water in the microwave. I drink a lot of tea.

That's only second to...

whatever someone wants to get me, because they thought of me while they were getting it. I do think it is the thought that counts.

But if you combine the two, there is the perfect gift!
