Feeling some intense nostalgia right now.

In kindergarten, every kid had a 5th grade “reading buddy” who would come in once a week and read to you for a class period.  Mine was the older sister of one of my then-classmates.  I didn’t keep in touch with either of them after middle school, when the younger sister and I went to different high schools.  But I had gone all through school with her, and knew her family, and we shared a lot of the same friends.  A lot of connections there.  So I happened across her just now on Facebook, and saw she was tagged in wedding pictures, which turned out to belong to her older sister/my kindergarten reading buddy.  That was just so crazy to see.  She’s married?!  Suddenly I feel so much older.  She was several years ahead of us, but I still considered her a sort of peer.  What’s more, she now teaches at our old elementary school and had tagged my 3rd grade teacher (now her co-worker) in a status.  I can’t seem to wrap my head around this for some reason.  I don’t know.  Sometimes the concept of time just presses in on me and I can’t do anything but contemplate it and marvel at it and accept that it is always going to astound me.
