When i grew up i was told not to talk to strangers and dont get into their cars...

Be bloody careful and check them out first. Not check check them out though, just check them out

Good point as I use Uber here and there. I do try to check them out as best as possible.

Ask the driver if he wet the bed as a child, likes starting fires and likes killing puppies. If the answers are all yes, don't get in.

And stay away from someone offering candy but go to a strangers houses on halloween

I know we do talk to stranger's every day.
