If you have never talked to the girl despite being in the same section for three years, sending her a message on WhatsApp could be a good way to initiate a conversation and get to know her better. However, there are a few things you might want to consider before sending the message:
Be respectful and polite: Start the conversation with a friendly and respectful tone. Avoid any offensive language or behavior that might make her uncomfortable.
Find common ground: If you share any mutual interests or have something in common (e.g., a class, a hobby, or a school event), you could use that as a starting point for the conversation.
Keep it casual: Since you have never talked before, it's better to keep the initial message casual and light-hearted. Avoid diving into personal or sensitive topics right away.
Avoid coming on too strong: It's essential not to overwhelm her with too much information or attention at once. Take it slowly and allow the conversation to develop naturally.
Be patient: If she doesn't respond immediately or seems hesitant to engage in conversation, don't get discouraged. Give her some time and space to respond at her own pace.
Respect her boundaries: If she doesn't seem interested or asks you to stop messaging her, respect her wishes and give her the space she needs.
Don't make assumptions: Try not to make assumptions about her based on her social media profile or appearance. Keep an open mind and let the conversation reveal more about her personality.
Be genuine: Be yourself and let your true personality shine through. Authenticity is important in building meaningful connections.
Consider common friends: If you have any mutual friends, you could ask them about her interests or hobbies to find more conversation topics.
Remember that initiating a conversation with someone you've never talked to before can be nerve-wracking, but it's also an opportunity to make a new connection. Be confident and respectful, and don't put too much pressure on yourself. If the conversation doesn't take off right away, that's okay; not all interactions will lead to deep friendships, and that's a normal part of social interactions. The most important thing is to be genuine and kind in your approach.
