DS's 10th birthday is coming up and he's decided he wants a whole class party with the exception of one child. They've never gotten on, the boy has always teased DS, tried to turn his friends against him, the other week he was throwing stones at DS whilst he was on his way home from school. I can understand why he wouldn't want to invite him but it may cause more problems in ths long run between them. I can only imagine what his parent's will be like if their son is the only one not to be invited. DH thinks it would be cruel not to invite him despite how he treats DS, would I be being unreasonable to let DS do this?
