MONEY IS THE ROOT OF ALL EVIL....rumbling of the week

My house recently just installed a new aircondition with a split air system. In other words, once the main switch is on, every room will get the cool air. However, the main switch was wrongly attached to the Master bedroom and it will be adjusted to the hallway soon.
So my fellow house (owner of Masterbed room) was overwhelmed with the new air conditioner and had it on overnight. Despite the cool weather temperature last night was 17 degrees celsius and I had to "endure" the cold air blasting at my face while sleeping.
Being a sensitive new age guy like him, I tried to hint to him like " you know, it's really cold in my room and i have no choice but to open the window and let cool air escapes".
The reply i got from him is :" i'll adjust the temperature then".
Fine, i think the adjustment got way too far. I had 2 blankets on and my flannette pants on. What's more, i even had to use a poster cardboard to seal off the air vent.

Woke up early in the morning 7yish (woken up by the cold obviously) and the air cond wasn't off till 9yish until i knocked on his door. And i asked him does he actually needs the air con and i showed him my room with the sealed air vent plus also emphazised that i;m not gonna pay more than 10 hrs of electric bills everyday of this.
He gave me the reply was " up to u".

what thes?? my internet is *ucked up* brb!
