Size-shifting randomly on set intervals, and the ensuing fun/annoyances

I've been imagining what it would be like if every so often (Every day? Couple of days? Couple of hours? Who knows!) my size randomly changed. There could be a range, but it would vary pretty widely. Maybe 3 inches to 100 feet. And maybe, to keep things interesting, the "randomization" tends towards the extremes.

Infrastructure would be a pain, since obviously what works for one size rapidly fails for another. Having a house that's often a bit too scaled up, just in case. Having multiple doll houses inside that house for when I'm different levels of small. Stepping outside whenever it's time to change I to make sure I don't destroy the roof. Running late on a walk home, and shrinking just down the sidewalk. What was once a less-than-a-minute jog will quickly become an hours-long trek. Growing while having dinner and finding that my once ample serving is now less than a crumb.

In a more NSFW lane, macro antics would become just that much more risky. Sure we're the same size now, but I'm scheduled to change pretty soon. If you get unlucky and I grow even bigger, will I treat you the same as the tinies we're passing between each other now? It might be worth it to stay and find out, because if I get unlucky, you could make me that tiny.

What if I never grow more than I have room to? You're having just so much fun with me tiny, that when the time comes for me to change you shove me somewhere tight so that I won't be growing too big anytime soon. Just beware, because you'll have to let me go eventually, and the next time I'm big I'll be repaying the favor. And maybe if I shrink with you inside me, you'll shrink too~

All good things to think about, and as I think I've demonstrated, there's lots of ways that you could toy with this idea by changing up the rules. I'll leave you with one last thot before I turn this over to you: Me and someone my size, anxiously waiting until the clock strikes 12:00. Then, I'll change size and we won't be equals anymore. We spend the minutes telling each other all the dirty things we'll do if we end up as the big, maybe secretly hoping we each end up as the tiny after all that teasing, until the moment comes... and I grow a single centimeter. It looks like we'll have to reschedule for the next size change.
