Like poseia said, he needs you to come for whatever reason. He is using your curiosity as a means to ensure you go. Its just like talkin to a trick, dont act interested the shit will work out. Get some information out of this little polish guy and see what you get, worst case he sticks to his guns with his approach and dosent talk, best case he spills just a little and maybe a little more. Either way if you end up going I would be strapped or at least have something on your ass if you aint got no kinda gat.
