Kids again

Today it was my turn to receive two subsequent groups of schoolkids. My not too helpful colleague set out the bare necessities the day before, like chairs for the kids, but I had the joy to put up all the rest this morning beforehand. I'm always very nervous, it's not really helping to have to set up laptop, beamer, tables to put it on, struggling with one of the tables to set it up right.
Fortunately the visits themselves went okay. The kids had a good time, that's what counts. But I do feel somewhat exhausted now.
