A new pair of Battery

Today huh ? not a good or a bad day either ,

Started with super sleepy morning , filled with very hard bastard math test , ended with super extremely hot room cause i dunno why my air conditioner started to turned off by itself . 

then i check the remote , it is supposed to be filled with 2 battery right ? then why the hell there's just 1 fucking battery !? i ask my lil bro .. he said nobody get inside my room .

so ? how the hell my stupid air conditioner remote can be used with just one single battery .. little bit weird huh ? it's been 2 months i didn't check the remote battery

well it must be a miracle 

anyway i just bought a new pair of battery
