Selfie Safety: Think Before You Click
{By Ravi, Class XII}
In today's digital age, capturing the perfect selfie has become an obsession among youngsters. However, this craze has often led to accidents and even loss of life. It is crucial to understand that safety should never be compromised for a photograph.
Firstly, avoid posing near moving trains, vehicles, or wild animals, as these situations are highly risky. Always be aware of your surroundings to prevent mishaps. Taking selfies near stairs or drop-offs can lead to fatal falls and must be strictly avoided. Moreover, casually posting selfies on social media without considering privacy risks can invite unwanted attention or threats.
Remember, life is more valuable than any selfie. Let us pledge to be responsible and promote safe practices while enjoying photography. Think before you click safety first, always!
