Went to the tailor

So, I figured I would get all of my pants shortened while I was here because its cheaper and none of my pants fit me because I have wee legs. After class, still in mu uniform, I bring some pants to a tailor that I found behind the seven eleven near campus. I try to use some Thai to tell them I have pants theyre too long, blah blah blah, and the woman looks at me with a very confused expression on her face,  the man who was fixing his motorbike in the shop laughs hysterically to himself for 3 seconds and looks at me and says "Tell me what you want and I'll tell her." So I'm putting jeans on and they tell me to roll them to the length  I want and she hands me a pin so I can pin them. They tell me I should come back in an hour. 

I come back in an hour and the woman isnt there but I see my pants finished and I see the man, still working on his motorbike. He looks at me and the only words I understood him say are Nacseuksaa (Student), and farang. They hand me the pants and then she realizes she only got halfway through one of them, so I take a seat while she is finishing up and the man is making small talk asking me questions. At one point he asks me where I am from, which, when asked in certain manners I have learned my answer should now automatically be, "I'm from America but my mom is from Lopburi" After I say this he looks at the woman sewing my pants and say "oh! loog kring" She looks at me, then back at the man and shakes her head no, at which point he gestures very specifically at my neck, and I realize he's looking at the necklace I was wearing which is my mom's Buddhist amulet from when she was a girl, and the woman still looked very doubtful. In fact, she told the man that I was not half Thai looked back at me, shook her head, and gave the man a look dripping with sarcasm. I cannot pass, and I am not sure how I  feel about that.

And now, all my pants fit me.
