Yes, I agree monthly is a good idea. They'd appreciate it.

[It would give them something to look forward to, and might make the more unruly ones manageable, if having a monthly trip on the horizon becomes an incentive to behave. Still, Amos's enthusiasm (even a genuine smile!) on the whole thing surprises him; though he understands his reasons for it, he still never would have guessed children would be his soft spot.]

We can discuss it at a later time, then. Perhaps you can decide on the next location we take them to? [Unless they want to return to the beach again and make the most of summer while it lasts, of course.]
