As a preteen, I couldn't resist the siren song of AIM, or AOL Instant Messenger. I'd hear that "door opening" noise or a message notification and rush to my computer, eager to see if the sign-on was my best friend or my boyfriend, both who were equally tethered to AIM at the time. (Naturally, all of our screen names usually contained the name of the person we were "dating" at the time ― NicksGirl4Eva88 was the height of romance in middle school in 2001.)
