Why does everyone in the metro state at me??

I'm usually normally dressed but people keep staring at me. This one time I was just sitting and I suddenly noticed a woman in her late 20s staring at me like in a bit wierd way cranking her neck out. Then I noticed a man who was sitting right next to me was staring at me too and then I realised everyone was sort of staring at me at my face in particular like in awe or something it was soo wierd

And this woman was apparently a couple with the man and when I noticed her cranking her neck out and stared back for a few seconds he like suddenly noticed and tried to look away and held her hand but the thing is my art portfolio was right next to my legs leaning on me and when I grabbed it as it moved a bit because of his shifting he like angrily pushed it away of sorts like what did I do???? I'm just sitting here

I've had so many wierd experience like these why do people state at others soo much?????
