Occasionally she'll try climbing something else: ladders (yawn!) or tree stumps (boooring!) or stairs (you're kidding, right?) Or she'll lay claim to the entire swing set so that she can make them all go at particular intervals and run back and forth to keep them going. Slides are now just a quick way to make it down to start climbing again.
Every few inches higher she'll yell out, "I'm a big girl now!" and then follow it with play-by-play commentary, "I'm going to the tippy-top!" or "Up! Up! UP!" or "I'm THREE! I just had my birthday!" I used to think she was shouting these things to me, but I recently realized she's informing everyone on the playground, including the adults. And if she doesn't get enough in reply, she'll climb down and walk right up to someone (sometimes 5 years old, sometimes 55 years old) and repeat herself until she solicits a comment.
I pretty much love it all. Even the part when I'm gasping internally as she climbs higher and higher and cackles with laughter, showing off by bouncing while only holding on with one hand.
Annabelle is a riot.
