I want to feed my friends crickets
Why would you feed your friends crickets?
Because I want to utilize all resources to save mankind, and crickets are healthier than chicken.
You shouldn't feed your friends bugs without their permission. They'll get upset and feel disgusted at what you made them eat. They won't trust you around their food anymore.
I know my friends will get over it.
It's a breach of your friends' trust. If they got to know about it, they'll end the friendship. You should leave them alone.
