My wife was almost kidnapped today.

I was on my run, when I get a message from my wife, “I was almost kidnapped”. I immediately called her to ask her if she is safe and what happened. She tells me that a guy came up to her stuttering to talk to her about Jesus. We are Christians so she had an open mind. He goes on this rant about how he died years ago and saw Jesus and how Jesus turned his life around. Before this she said that another man and him would walk around the store separately and meetup to talk and then split up again. While she was talking to this man, the other man tried coming up behind her. Thankfully she avoided him and moved out of the way. After she avoided him he bumped into her on accident. She backs up and notices he’s holding a tiny spray bottle in his hand. she said it was clear and was holding a white milky liquid that had the viscosity of water. She looks at the man and he looks at the other man, freaks out and immediately leaves the store. Anyone know what the liquid could have been? My wife is safe and now home. She stayed in the store for a while and then went immediately home.
