Have you ever notice stuff like this?

You have housemates who are couples.
You are inside your closed room, but you did heard them arguing a bit inside their own room. (Our unit have very thin wall).
After awhile, you can heard someone sitting at the living room watching video clip or dramas and somehow you know it’s the guy.
And then in the kitchen you heard some noice of someone tidying the kitchen but the sounds is different then the usual tidying sounds, because it sounds angry. And then you know right away that is the girl getting pissed at everything because of the argument with the guy…
But then you heard them still talk normally with each other, no arguing, but you still can sense the “upset tones” from the girl’s voice, while the guy’s voice sounds like he want to avoid any further arguing….

It is very interesting to observe people’s stories. I have encountered many interesting story inside the train I took for travelling to work or anywhere else.
I managed to encounter these stories is because my ears always managed to catch on any interesting conversation, even while I am on my phone reading manga. My friend would ask me why she never seen/heard/experience anything interesting inside train or anywhere else. I would say that it’s because I am interested in observation of human relationships, behaviour, and love to deduct some conclusions about the situation I witness…

There’s one time I encountered a situation (actually I just eavesdropping) where I should be helping, but too scared because I know I will be putting myself in danger if I try to help.
Inside a quiet train, I saw a man in his 30-40s and a woman in her 60-70s…
They sounds a bit angry.
They were saying, “those people are bad people, they are so mean, we just love each other so much, why they try to separate us?”
Upon hearing this, I thought, oh, they are couple with very big age gap, hum… well if they love each other so much, then people should just bless them…
After they keep saying bunch of lovey covey words to each other, the guy suddenly said something that made me think “Huh!? Wait a minutes..”
The guy said, “you see, so many people are against me being with you, but I love you a lot, and you love me right? If we want to be together, I will need some money, I currently have this much (very little amount), I need around (big amount) more so that I can stay together with you whom I love.”
The woman said, “I love you, I want to stay with you, but I don’t have that much money.”
The guy said, “Hm, can you ask your brother for the money, he have lots of money, we really need this much money to stay together, if we don’t have this money, then I won’t be able to stay with you, but I love you.”
The girl said, “But I don’t think my brother will give me the money, he is angry right now.”
The guy said, “Do you not want to be with me? Should I break up with you? I love you, but I really need the money, please honey, try calling your brother, ask him for some money, you’re his sister, he will give you the money”.
The girl said, “I want to be with you, I love you, I will call my brother.”
And then their stop arrived, so they get off from the train first. (Btw, they kissed a lot)…
.
Honestly I already suspicious that the guy is scamming the woman when he asked for the money, and when he insist her asking money from the brother, that’s when I am sure of it…
But the guy looks like drug addict, and scary, so I just can’t bring myself to step in and reprimand the woman. I even texted my brother to get advice, and he told me to never ever get involved because I will definitely get in bad situation, that I might even get killed if things go wrong…
