It is just plain creepy.
But a few questions…How the hell does someone go missing and no one checks WHERE THEY LIVE?
How did no one like check on her if she wasn’t making rent?
How did the tea still stay? Wouldn’t it evaporate?
I remember there were japanese soldiers found a couple of years ago in a jungle somwhere still guarding their posts since world war 2! They must have been in their 80’s or even 90’s!
Also, to answer your question, I’m sure there was no rent to be payed. In Europe, most people own apartments like Americans own houses. Yet, they are still referred to as apartments. There’s no such understanding as “townhouses” like we have here in USA. So she lived in an apartment which was entirely hers, and she didn’t need to pay any rent.
And I guess she was just a really lonely old woman who didn’t have relatives or many friends.
Also, it only said the cup was there, not the tea. I bet the tea did evaporate heh.
