And come see us Saturday at 7 at Marysville Historical Society down on Armar Road! Love to see you there!

I hope you’re all having a better morning than me. But to be fair, doc has been outstanding and the folks here at the VA Hospital are wonderful.

Good luck to all our math students on their finals tomorrow. Here’s some donuts to keep your spirits up as you study today. Wish I could be there.

We thought it might be fun to get out our throwback jerseys as all our teams are in the playoff picture as of today. Recognize all the players here? Comment below! I’ll post the back picture later…

I miss arcades.

Can you name all four ghosts? I mean, from memory, without help?

New T-shirt Friday!

Also my holiday package from Nürnberg arrived yesterday, after significant delays due to tariff inspections. Grr. Sharing with my coworkers today!

Happy trombonist. My chops are improving.

This is fun.

Book festival! Lots of families and young people here to celebrate books in Poulsbo. Everyone here has been so welcoming. And J even marched in the welcoming parade, led by the marching band!

Just helped a poor knight in need of math help. She solved this and we dined on Halloween candy!

My first in person rehearsal since March 10, 2020. My sight reading wasn’t as bad as I feared. My chops, however, are. My lips are hamburger now…

Had a great time playing with Marysville Community Band again. (I work to 8 on Tue/Wed so Evergreen Community Orchestra isn’t an option right now😢)

My weekend. Hey, Monday is Diwali! Also, no to Trump and the Democrats alike, and to Musk and Bezos and Dimon.

Had a great weekend with J at the Bigfoot Book Festival in Redmond! The place was hopping and we ended the day all smiles.

Got sent to the hall for wearing this! It’s fun bringing in more than just math shirts. Sharing the love with other departments here at the Instructional Center brings me great joy.

There’s an energy on campus during move in that is really powerful. Young people excited as they move out of their parents’ orbit and begin a college life full of promise. Happening right outside my window.

I’m feeling good today.

All detainees must be immediately released and given means to return to the place from which they were abducted, and their families and loved ones given full information about their status (their health condition, estimated time/location of return, and means to contact the detainee now).

Weekend trip to Leavenworth (Washington) was a hit! For those unfamiliar, it a Bavarian-themed town in the Cascades. There’s lots to do in the area: hiking, rafting, and the like. We just walked around town, stayed at a lovely pension, had a great dinner.

Casual Friday, and the end of Summer Quarter. Thought I’d pop in to the Biology Room here at the IC. Man, this place has everything!

New t-shirt Friday takes me to (natch) the Chemistry Room here at the IC. What will my next shirt be? Hint: it involves multiplication AND division.
