If someone calls your phone looking for someone you know, don’t give out the persons info. Instead, take a name and number and give it to the person you know
If you get a call from someone looking for a friend/family member or their information, even if you don’t get a name and number of the caller tell your friend someone called trying to find them.
Just because you didn’t give the caller the info does not mean someone else didn’t give the caller the information. If it’s a stalker/abuser etc. trying to find your friend or family member then they won’t stop at you. Give your friend/family member a heads up! It might prepare them for or save them from a dangerous encounter.
