what is the help sign

The help sign referred to in the question is likely the "Signal for Help" or "Violence at Home Signal for Help". It is a single-handed gesture that can be used over a video call or in person by an individual to alert others that they feel threatened and need help. The Signal for Help was created by the Canadian Womens Foundation in 2020 as a tool to combat the rise in domestic violence cases around the world as a result of the self-isolation measures related to the COVID-19 pandemic. The gesture involves making an open hand, placing the thumb across the palm, and closing the four fingers into a fist. If someone sees this signal, they should reach out to the person safely, acknowledge their experience, listen, and let them tell you what they need. They should also refer them to services or offer resources, as needed.
