i talk out loud like you still around

I've got a cup of latte placed in the left side of my desk. I sip it in every 2 minutes. I never manage to drink it fast or in a short period of time like normal people do, I can take more than half an hour to drink it all and even if it gets tepid I will still drink it. At college I tend to buy a cup of latte in my break time, which is 30 mins break if I am not wrong.. but I never finishes it in time and I am not allowed to drink it inside the classroom.. which is one of the most annoying rules ever.
