LOL! Well...may I remind you this is for entertainment purposes only and I am no expert on people and their habits. This all may be presumptuous.
The fact that you are a tea and coffee drinker means there is a duality to your personality. There is a tea drinker in you who is calm, patient and deep thinker and planner. The tea drinker in you will take time to analyze, study and observe people and see things in people they do not even realize or is aware of about themselves. Your insights are always sharp to the point some people who don't know you might take offense. And of course, you have to be a very complicated and intricate individual that is hard to guess. So you drink coffee too. But because you don't drink coffee often and everyday, but only when you need it, shows that you are sometimes a hot tempered person when provoked in the wrong way, though you do well to hide that side of you. You enjoy the different styles of coffee means you are not closed-minded, you don't like restrictive and limiting lifestyles and like to explore and discover different things. You like to explore all the options the world and life throws at you. You joke and play pranks to entertain your mind so it doesn't rot in boredom and everyday dullness.
You prefer to drink with milk...Well..I guess you're not strongly lactose intolerant! However, some dairy products and the cultured ingredients does not always work well with you. You are somewhat concern for your healthy intake, so you would drink things that would help your health, but could care less for it if it wasn't necessary.
How's that?
