Irrational Sadness

Today at work I attended a play. I was looking forward to the play since I knew almost all of the kids. However, at the very beginning I had this thought that I'd never get to see Katherine and Samuel in an elementary school program. Realistically, even if we hadn't lost the twins, we (I) plan to homeschool so our kids wouldn't be in these plays anyway. I tried telling myself this, but it didn't make the sadness go away any. :( It became a tad difficult to focus after that.
