Am I being paranoid?

if he was russian than id say he was just trying to start a business because they always start business haha not trying to sound mean or anyhting but it might just be a guy starting a business if he gave you a card than maybe you should check it out a little maybe look up the number online see if its actually a business if not than its most likely a robber and beat his ass witha monkey wrench

If you are cultivating cannibis, you shouldn't be able to see your crops from your windows. thats just stupid. So dont do that.
