Colorful things-
Fireworks. I LOVE fireworks! My favorite place to watch the MK fireworks used to be in Fantasyland, where they fireworks seemed to be exploding directly overhead. I'll probably never see these shows from in-park again as the shoulder-to-shoulder crowds are terrifying, but I do love a good fireworks show.
Christmas lights. We leave the multicolored icicle lights up on our front porch all year round. I love coming home to the warm, soft, colorful glow each night.
Pens. I still grade quizzes and exams by hand, and have a set of pens in 12 different colors that I use for this. I keep hoping that the cheerfulness of magenta ink might put a smile on a student's face!
Music things- I'm not terribly musically-attuned, but...
Being able to get in the car, open the windows (and turn up the heat in winter), blast the radio, and drive. Yup, mostly about the driving but it wouldn't be the same if I couldn't crank up those oldies tunes so I could SING while driving!
Ballet scores. As many of you might remember, my DD was a trained ballerina who danced with a couple of companies when she was in her teens and twenties. I can hear certain scores (whether scored for a ballet or just written but used in different productions) that take me back to specific times/places with some very wonderful people. It's like it's engraved on my heart. Isn't it crazy, how we associate music with emotions and experiences?
Listening to my SIL perform (sing/guitar). I am not a big fan of his preferred genres, but I truly enjoy going to watch him perform, seeing him do what he loves.
