history: I was really mad with my housemate last night. She got in really late and made loads of noise. I was really mad with my housemate last night. She got in really late and made loads of noise Oh that can be annoying! I guess in her defence it was a Saturday night? But still_comma_ it doesn't take much effort to try to keep the noise down even if you do get in late! I hope you were able to sleep okay. 
current: Yeah I agree, we both work shifts though so sometimes I have to work all of Saturday day and I always make sure to keep the noise down if she's had to work a Saturday. Thank you.
next: Yeah, like you suggest, it is the little considerations of the other person's needs that can make the difference between an okay and a really good flatmate.
