Four days in, still can't explain why it works

Only four days in as I write this and I already don't have a great explanation for why the one conversation I've got going has worked this well and it startde because she commnted on something specific in my profile instead of the usual generic opener. we've talked every day since, somemtes a few messages, sometimes a long back and forth that somehw eats up an entire hour. Too early to say much more but it's enough to make me want to keep checking back instead of forgettnig the account exists
