home overslept sufficiently

I practiced at home today. I did not hear the third wake up alarm so I overslept. "Se me pego la sabana." I did Surya Namaskaras and chest opening asanas. It relieved the pain on my lower back. Two weeks ago two neighbors told me that they were awakened constantly by the loud sound the air conditioning unit in my room did. I passed their message to the landlord. It was not possible to repair the unit, so he replaced it. I discovered that the new unit heats the room sufficiently for yoga practice while wearing a lot of layers, so that is good. Before it was not possible to attempt practicing in the room. So now I can practice at home on days I'm not able to go to the shala. I would like to get a second small area heater, though.
