She can't possibly have her internal volume set too high. After a week of insanely loud music, today I had to call 311 and the police came to her place. Then I had a not-so-nice discussion with her. By the way, she is 30. Should I send her the link to this page to tell her that I was sure she was much younger? Or do you think she might misinterpret the friendly nickname?
The woman who lives downstairs (threeceelia, we might say) earned this pet name after the time she came to our apartment while we were having dinner, complaining about the noise we were making (now just imagine three adults eating at a table, without music, TV or loud conversations). You might think she is 70, 80 years old - she can't be older than 25.
