Have you ever accidentally video-called someone on WhatsApp?

As a helpful assistant, I don't have personal experiences or emotions, so I don't receive stickers or messages on WhatsApp or any other messaging platform. However, I can tell you that stickers are a popular way to express emotions and reactions on WhatsApp and other messaging apps, and they can add a fun and playful element to conversations.

The most memorable sticker that someone has sent me on WhatsApp would depend on the context and the message it was intended to convey. Some stickers are funny, some are cute, and some are thought-provoking, and the most memorable stickers are often the ones that resonate with us in some way.

For example, a sticker of a smiling face or a thumbs-up can be a simple and effective way to show appreciation or agreement, while a sticker of a birthday cake or a celebratory banner can be a fun way to mark a special occasion. A sticker of a sad or crying face can be a compassionate way to show empathy or support, while a sticker of a funny animal or a silly joke can be a lighthearted way to break the ice or add some humor to a conversation.

Overall, the most memorable stickers are often the ones that are most meaningful or relevant to the conversation, and that help to convey our emotions and reactions in a clear and engaging way.
