I bought my boyfriend a heat-sensitive mug for his birthday.
It displays “HOT” or “COLD” based on the temperature of the contents.
We met in the coffee shop that he worked at. After months of not having the courage to talk to him, and through the power of online social networking, we started talking and then… dating. :)
So I thought this was an appropriate gift.
