Conflicted

I'm feeling a bit grownuppy conflictedness. (although when I use a phrase like 'grownuppy conflictedness obviously I am NOT a grown up) One of my Brownie parents mentioned tonight that he leaves his two younger (younger than his 3rd grade Brownie daughter) sons at home while he walks down to pick her up. Now I'm assuming we aren't talking about more than 15 minutes, BUT let's realize that these kids are younger than 8. On the one hand, it is only 15 minutes... what could happen. On the other hand... it is 15 minutes and they are young kids! So here's my conflictedness... what do I do, if anything? Maybe nothing... I don't know but I don't like feeling worried...
