Now, I'm not saying that I don't like coffee because I do, a lot. My associations with coffee are more frenzied than relaxing. "I need to stay up until 3am" or "I need to wake up, or I'm going to miss my flight."
Tea, on the other hand, has more relaxing connotations. "I'm going to sit and write some letters" or "My friend is coming over, I'll put on a pot of water".
Anyways, I love tea, but not more than coffee- just differently :)
