While it’s not strictly a Thermos, I have been enjoying the water bottle I got during the Priests vs. Seminarians game a Sacred Heart Major Seminary a few weeks back.
For a proper Thermos, I’d have to think back to my childhood. We had Thermos-like things in our lunch boxes. But mostly, I remember that my Dad would fill up a Thermos with coffee to take with him to work.
What are your Thermos memories?
