First impressions matter, even when you're anonymous. A creative opening line immediately sets you apart from the hundreds of people just saying 'hey' or 'asl'.
Try starting with a fun 'Would you rather' question. For example: 'Would you rather have to loudly sing every time you read, or softly whisper every time you speak?' It's absurd, fun, and guarantees a reaction.
Another great approach is the controversial (but lighthearted) opinion. 'Pineapple on pizza: culinary masterpiece or absolute garbage?' This immediately sparks a playful debate and gets the energy flowing.
If you prefer something deeper, ask about their day but with a twist: 'What's the most interesting thing that happened to you today?' It forces them to think beyond the standard 'it was fine' response and usually leads to a great story.
