Nikolai doesn’t like certain phrases, for whatever reason.

If I ask him to go on a hike with me, he will say no immediately and will not be gainsaid.  If I ask him to take a trail-walk or a nature walk, he would love to.

His other trigger phrase is go to the beach.  Often, my idea of a good time is ditching everything and driving the 2ish hours to the beach, and just wandering around some small town or whatever.  He would probably enjoy it, but refuses to go to the beach.  I asked him if he wanted to drive to the ocean and he was instantly delighted.  Other possible substitutions for “beach” that my dad suggested: sand-water place, and big splashy.  I think Big Splashy works best.
