I belong to an art group and at the end of each year the people who run it entertain the group at their home. However, this year I have been unable to go to the last 4 weekly meet ups because of ill health. One of the group contacted me to say that they had all received an invite again this year, but I have received nothing. Am I being unreasonable to expect one or should I just bite my tongue and return to the art group in the autumn term as if nothing has happened. I would not be able to go because my illness will take several weeks to get over.
