Saturday with Einstein
by Mona Gedney

I knew very well that I was making a mistake when I agreed to attend the meeting with Kristina and Joel. I do not particularly enjoy belonging to clubs; I greatly prefer doing things with only a few friends or even just spending time alone. Still, they are my best friends, and I do like our town, so I agreed — very reluctantly — to go.

We live in Mount Dora, which is the proud possessor of one high school, one middle school, two elementary schools, a well-used library, a thriving downtown district, and a handsome new community center. It was the new community center that had created my problem. The director had decided that sponsoring a service club for teens would be a splendid idea. It was my misfortune that the director is Kristina's very enthusiastic aunt. And so it was that I, along with approximately two dozen other misguided souls, attended the organizational meeting for the Dora Do-Gooders. I had explained to Kristina that I would attend the first meeting as a show of support for her aunt but that under no circumstances would I commit myself to doing anything more than that. Therefore, I was stunned to receive an e-mail from Mrs. Maguire that thanked me profusely for signing up to be a part of the first major undertaking of the club, an entire Saturday devoted to service projects for citizens who needed help.

I glared at Kristina reproachfully throughout our first-period Spanish class the next morning. She had responded to none of my calls or texts nor my outraged e-mail, and this morning she studiously avoided meeting my eyes, doubtlessly glad that the alphabetical seating arrangement meant that she was across the room from me. I also noticed that she had entered class at the last possible moment — and that Joel was also trying to catch her eye. I grinned a little at that.

The results of my confrontation with her after class were unsatisfactory. Kristina apologized but then shrugged, adding, "What could I do? She's my aunt, and she needed volunteers for next weekend. I had to help her."

I was about to say that Kristina could help her all that she wanted but to leave me out of it when Joel grudgingly said that he would help. Mrs. Maguire had tutored him in algebra and had been very kind about it, so he supposed he could give up one weekend to help. I felt no such obligation but being rude would not be wise. After all, math is not my strong suit either. Who knew when I might need Mrs. Maguire's help?
