Today around 12-1 PM a guy in his early - mid 20s who seemed to be Eastern European knocked on my front door. He was dressed fully in navy blue and had a black backpack. I wasn't expecting anyone plus i'm under the weather so i asked through my door camera what he needed.

He asked for a glass of water or a water bottle and if i had a few minutes to look through a picture book about his home country and his experiences there.

I found this entire request very strange and told him about a gas station just down the road that has a water fountain outside. He asked again if i would mind letting him use the restroom quickly and i declined.

Was this something nefarious? a scam to sell me some travel/book thing about his home country? just a weird guy passing through?

Any input would be appreciated as i'm a bit perplexed.
