Is This Anything? 16
When people ask me if I play chess, I usually say "I know how the pieces move." And I think this is much more helpful than e.g. "I'm not very good", which could cover a very large range of abilities depending on modesty: "I know how the pieces move" succinctly conveys 1) I am able to play chess with you 2) I don't know any strategy.
I often want similar phrases for other activities, ways to unambiguously convey how good/bad at something I truly am, without the added layer of self-presentation questions. I suppose in this case it's easier because I'm bad at the thing: "do you play chess?" "yes my ELO is 2000" would also convey true and precise information, but is harder to say without sounding like a brie.
Organizing group-trips is incredibly costly for the one person who organizes, both in terms of time/effort/energy and even financial risk or carrying costs. In theory you could split the work between multiple people but in practice this never seems to work. It's also repeatedly the same person in each group who does the trip-organizing.
How would you feel if that person charged, say, 20% of the trip cost as a tip? Friend-of-the-blog H says everyone would hate this, and I assume he's right. But the alternative is not having trips at all, because nobody is motivated enough to organize them.
