I totally mixed up the names and paperwork of two students today and even went on a home visit of one student with the other student's paperwork.
There was nothing I could do once I figured out my mistake but to admit (to all the people there - 2 teachers, 1 student teacher, 1 translator and 2 mothers and 3 kids) that I had the wrong paperwork - and ask mom to come by and sign the correct paperwork at school tomorrow.
I had all kinds of signs, but ignored them all. My realization was slow, but I guess the upside was that I did not have mom sign someone else's paperwork. I did finally figure out my mistake.
At least I didn't have to use a lifeline :-)
