Her husband, Ben Affleck, has a Twitter account, but don’t look for Jennifer Garner to be Tweeting any time soon.
“I have an official Facebook page. I’m not on Twitter, Instagram,” she tells PEOPLE.
“I have a couple of reasons,” says the star of Men, Women & Children, who posed with costar Kaitlyn Dever for PEOPLE’s behind-the-scenes portfolio at the Toronto International Film Festival.
“One, I don’t want any more guilt coming from my phone or computer. I have the hardest time answering emails, anyway, so the last thing I want to feel is indebted to my phone or computer. So it’s time.”
“And the other is, what would I Instagram that people would want to see. There is nothing I would put out that people would want to see. It’s probably best to stay away. They don’t want to see me and my mom friends after kindergarten drop-off.”
In Men, Women & Children – a movie about how the Internet affects people’s love lives – Garner and Dever play mother and daughter. “It was so easy,” says Dever. “I feel like we’re owed one more [film],” adds Garner.
