Stranger acting strange. Huh!

Hi SG! Basically this guy adds me from nowhere and I start talking to him. This is how the conversation went:

Me: Hi

SomeOtherGuy: hi

Me: May I ask why'd you add me?

SomeOtherGuy: for gg and trade

Me: ...What?

SomeOtherGuy: i wanna trade with you

Me: Where did you find my profile?

SomeOtherGuy: on madeupname friend list

(he made this name up)

Me: Hold on, I'm busy atm

SomeOtherGuy: ok from where are you ?

Me: Listen buddy, I don't have anyone with that name on my friends list. What are you trying to accomplish here?

SomeOtherGuy: wait

SomeOtherGuy: not madeupname on actualfriendofmine

Me: Oh great, so now you simply picked someone random from my friends list, someone who you aren't even friends with.

SomeOtherGuy: i added him

SomeOtherGuy: from where are you

Me: I have no proof of anything you say whatsoever, bud.

SomeOtherGuy: ok can we just do the trade

Me: LOL

Me: Dude we can chat all day long, give me one good reason, and then I'll trade with you.

SomeOtherGuy: 1 good reason for what

Me: For me to trade with a complete stranger who's not even being a bit honest and not telling me where did you find my
profile.

SomeOtherGuy: I finded your profile on actualfriendofmine friends list ok

Me: I call bullshit. Where did you find my profile, and why do you want to trade with me? And what is it exactly that you want
from me?

SomeOtherGuy: i want to trade my galil for your G3SG1 Polar camo

Me: I'm not interested. Anything else?

SomeOtherGuy: galil and tec9 for famas hexane

Me: I'm not interested in ANY of your items. Understood?

SomeOtherGuy: yes SIR

Me: Great. Anything else you require from me?

SomeOtherGuy: well

SomeOtherGuy: you have 2 SSG 08 Blue Spruce any of them go for free

Me: If I knew you from somewhere, I'd probably do it. But since you just added me and I don't even know what kind of person you
are, despite being a complete stranger to me, then the answer is: no.

Me: I am not interested in trading my items for yours, and I'm definitively not interested in giving my items to you for free.

Me: Are we done here?

SomeOtherGuy: yes bye

Me: Great, bye bye!

SomeOtherGuy: bye

SomeOtherGuy is now Offline.

So, what do you think? I don't believe he was trying to scam me or anything, but he kept lying to me and wasn't making any sense. Probably just fishing for some free items. I don't know, you tell me!
Anyway, just talk about it people!

Cheers!
