Tips for meeting your significant other's parents for the first time?

I’m always great with parents for some reason, and they usually tend to ask a lot about your life, getting to know who you are/what your plans are for the future, and if you’re good enough for their kid. Thankfully, I always look good on paper. Either way, I think if you haven’t been warned that they’re total assholes you’ll be fine because it’s hard to please people who don’t want to be pleased and there are a lot of parents like that out there, but kids are usually aware of how their parents are and try to prepare or warn you.
