If I had a dime for every interesting little toy Rosalie and Rosalind have given me over the years, I’d be a truly rich man. I haven’t used more than a tithe of them yet, but I keep them all against the day they come in handy. Not that I can tell you what most of the toys do. But every once in a while, when I’m about to go some place, I’ll get a message telling me to take one. And wouldn’t you know it, the thing turns out to be useful. It might be a tracker for some rare particle I’ve never run into before, or it might be some cheap but ingenious thing some local will find amazing and give me information I need. I usually have no idea what the mystery box has until the time comes. I just listen to my girls and haven’t regretted that yet.
