So she took an experimental medical treatment just so she could go to Hawaii? That's an AWESOME reason. I hope to hell you read her the riot act and are starting court procedures to get her kids away from her and her dimwit husband.
YOU are a moron. My daughter and son-in-law have no kids and are getting ready retire.
I asked her about vax risks and she said life is full of risks. The airplane could fall out of the sky. They choose to take this risk for their last wonderful trip to Hawaii.
I respect her and her judgement. I most assuredly do not respect you.
