Who called from 8084684020

Got a call in the middle of class. Don't know anyone from Hawaii so wondering why I was getting a call from them. I answered and no one said anything for 5+ seconds so I hung up

said they were from a national insurance foundation, asked how i was doing then hung up.

Probably that insidious "security" company out of Texas that calls about a billion times a year. They continually piggyback off other numbers that have been discarded.

Someone called me twice with this number. I answered on the second time. I thought it could be important since they called me twice, but no one was talking back, so I hung up.

possibly an alient. didn't pick up the phone because the phone waves might interfere w. my brainwaves
