"Grandma" for a moment

It was only about 15 minutes, but today I was someone's "grandma" (or 'special person' as the classroom teacher kept repeating).
Our school has been celebrating Grandparents' Day (Friday, today & tomorrow). This morning one of the teachers asked me & a couple of the other girls I work with to come down to her room later around 2:15 because she had a few students who might not have a "special person" show up & we would take their places. She did not want any of the students to be left alone without someone there for them. Of course, (can't you feel the tugging of heartstrings here) I couldn't say no, so at 2:15 I was off to her classroom. She thought she was going to have 5 students without visitors, but actually only ended up with 2 & I was one of the chosen ones to help out. I sat with my "grandson" as we watched the class video of activities they've done so far this year & made sure to 'ooo' & 'aaaa' over him whenever he was shown. I also let him read the book he had made to me (he was supposed to finish it with his visitor-his mom-but since she didn't show-he wanted to save it for home, so she could do it then). I asked him about his favorite movie (SAW-which I must say perturbed me quite a bit considering he was only a first grader!) & then we got refreshments. About this point, the teacher said "thank you" & that it was okay to go whenever I was ready. I finished up my snacks & told him that I was glad that I could be his "special visitor" & headed out the door.
I hope that his mom did eventually show up, but I was at least glad to be able to fill in for a moment just so he wouldn't have to be all by himself while the other kids were visiting with their guests. It wasn't quite this, but it was still quite rewarding.
