Some years ago, a person from high school suggested I join fb, as they all were on there, and "in touch". Well, most of them didn't talk to me in school, and they still didn't after on fb, nothing new. A bit later, something happened that really left a bad feeling about fb, and I just ignored it for a couple years.
But now, in an organization that see a lot of action there, so kinda had to go back.
