Your messages sound really stilted and like you're really nervous. They jump from one random topic to the next, without actually showing anything uniquely
you.
> But, well, I own a 5 foot long remote controlled floating dolphin. I gave up on being 100% sane long ago. Technically I am sane, but I do enjoy having fun toying around with things. I also drive a bright orange car!
What this says: I own toys, you should know about them! Also, I think I'm "crazy!" And I have an awesome car, look at my success!
It makes you sound kind of like you're filling your life with things because you've been socially rejected. If that whole block of indented text was your entire first message, then it's incredibly rambly and full of similar flags.
One of my most successful stream of messages went something like this: noticing that my potential date lived in Cambridge, I asked if they had explored the area (they said they were adventurous in their profile). When they responded with "Yeah, I've found some cool stuff", I then asked if they'd found the secret staircase that led to the lair of angry geese on the river?
This establishes both that 1. I've actually read their profile, and 2. I have some knowledge they would be interested in, and that they can share in.
Here's how I'd rephrase your second message:
I noticed from your profile that you enjoy a good cup of tea. Do you make your own, or have you visited a lot of different tea houses?
You're not overwhelming the other person with information, just asking a question that, if they've shown an interest, they're generally really happy to expand on. Don't treat your messages like emails or letters, but more like instant messages. Keep them short and easy to respond to, and let the other person tell you some of their story.
Edit: Also, don't ask so many things! It's hard enough for someone to want to answer a single question you ask them. Answering 3 or more is too much effort: if they wanted to start answering your first one, but kept reading instead, you've failed to convert, and by the third one they've likely skipped on to someone else's message.
