I clearly didn't use the best wording there, my bad. I simply meant that I would prefer to show appreciation as a response to something rather than pre orchestrated. So for example appreciation day is the first Monday of the month and the previous week a parent has paid me late, forgotten clothing and appropriate footwear preventing the group from going outside and then has picked up late making me late for an appointment messing my whole evening up. To "appreciate them" on the following Monday is the same as reinforcing a badly behaved child. I'm not going to be rude to those parents or bare a grudge but I'm not going to reward it and have them leave with a warm belly and a big smile thinking wow I really pushed it last week and this is what I get in response.
