What are things to keep in mind when couch surfing?

You need to be open minded because those that will give you a couch to sleep on might not be as you. [ they give you shelter and food but might be a lot more different that you ].
Be prepared for anything.
DO NOT, I repeat DO NOT leave matches / lighters unattended because there might be kids who can play with them and start a fire .. I had this issue with some ^^

Best to keep your money on a card and don’t keep a lot of money in your pockets. [ you don’t know who you can come across ]

I did this for about a minute. for me, they wanted sex. ewwww

There are some very weird people out there. Listen to your instincts. If something seems not quite right, it probably isn’t.

Couch surfing can be great. Key is to read the host’s reviews on the website. BIG indicator there. I once surfed at this guy’s place. he had no reviews. he was WEIRD. i only did this because there were 5 of us couch surfing with him, so risk was low.
