First, tikva is extremely friendly. She's bouncy, energetic and enthusiastic in a way that really lights up a room when she's in it. If I had a club and I wanted people to feel welcome in the club, I would have tikva act as the greeter, because you just can't help feeling like you're where you belong when you're with her.
tikva is adventurous and brave -- she's willing to take risks and she likes to try new things.
She's also thoughtful. When I want to get a clearly considered opinion of some issue, asking tikva is often a good bet.
These are some few of the many reasons that tikva rocks. If you want to know her better (and why wouldn't you?) her journal is often entertaining, too :)
