The burden to stop sexual harassment should rest squarely on the shoulders of the person acting inappropriately, but if you see sexual harassment while out with friends, there are things you can do to help the person who's being harassed. Drinkaware has started a social media campaign with the hashtag #OKtoAsk to encourage people to ask questions if they see something suspect, which is a mainstay of bystander intervention. The organization encourages witnesses to step in if it's safe and possible to do so. Here are some things to ask yourself, according to Drinkaware.

Is something dodgy happening? Don't be afraid of butting in if you have a gut feeling something is off. Is it safe to step in? You shouldn't risk your safety to intervene. If possible, alert a bouncer or bartender. Can you directly ask the person being targeted if they're OK? If you're nervous about talking to the offender, try to start a conversation with the person being victimized.

If the answer to any of these things is "no," it's a good bet to get security or staff involved. No one will blame you if you're in shock when you see something inappropriate happening, but if you have the ability to help, you can start with these questions.

“If people see someone being sexually harassed, asking them if they are ok can make a big difference — whether they’re a friend or a stranger," Drinkaware campaign lead Janet MacKechnie said in an emailed press release. “It’s time to put an end to unwanted drunken sexual harassment. Asking someone if they are OK and giving them support sends a clear signal that this behavior is no longer going to be tolerated.”

The next time you plan a night out with friends, keep your eyes peeled for anything potentially risky — you might be able to help someone get out of a dangerous situation. This shouldn't be your responsibility, but until we change our expectations and fully dismantle rape culture, sexual harassment will continue to be a thing we need to be aware of.
