A stranger is someone you don’t know. Strangers can even be someone that you have met in person before but do not know well.

Strangers can be people you have met on the internet but have not spent time with in person. You can have someone who is called a “friend” online, like through Facebook, Instagram, Snapchat, or another type of social network, but who is really a stranger because you have never met and you don’t really know them.

Sometimes, even staff and other professionals can be strangers the first time you meet them.

Remember, you may also be a stranger to someone else. If you haven’t met someone in person, or if they don’t really know you, you are a stranger to them.
