I am finding this hard because I don't think DS's teacher did a very good job this year. For Easter DS gave her an Easter egg. Her response "I'm allergic." Not even a thank you. I really don't want to give her anything! Do teachers really notice if a child in the class doesn't give a gift?

His teacher last year I gave a wooden Christmas decoration that said"peace." Fitting for a catholic school.
I had 3 teachers that were awesome, and one that was quite bad. I wasn't brave enough not to get her something, but noticed that DD put much less effort in to her present anyway.
