“I believe that’s a good thing to do because there are so many animals euthanized,” says the vegetarian, who also uses Twitter to promote other causes she’s involved in, including This Bar Saves Lives, a healthy snack made by a company that provides a packet of food to malnourished children in ­developing countries for each sale, and ­Invisible ­Children, a charity to aid victims of Uganda’s civil war.

“I really, really, really believe in having a sincerity behind my Twitter,” Bell says. “It’s my personal Twitter. It’s not a Twitter for work. I sometimes promote projects that I love on it, but I like interacting as a human being on it. If somebody says something cute or if somebody says something nice, I respond because I just believe that that’s the nice thing to do.”

Bell admits, though, to having heated Twitter exchanges with “unfathomably rude or ill-informed” people and ends up wishing she hadn’t taken the bait. Bell rues that her character flaw is that she’s a people-pleaser.

“I’m not super comfortable setting boundaries that disappoint other people,” the actress admits. “You can’t live like that because you’re solely doing what everyone else wants. And, sometimes, I’m tired and I don’t want to talk to anyone or do an interview or stand outside my car and meet another fan. Sometimes I’m just a human and am really exhausted. I’m OK now, setting those boundaries, but it’s hard for me because I’m scared people will think I’m mean.”

Bell credits her husband — whom she married in October of last year — for helping her curb her propensity to please people. That applies to her professional life too. Last year, the actress relished the opportunity to play against type in the moody lead role of The Lifeguard.
