MORE than 100 grandparents and parents of students at Horsham's Holy Trinity Lutheran School visited on Friday.
"I poured so many cups of coffee and tea," office administrator Sue Starbuck said.
She said the school invited each student's grandparents to attend , to enjoy the school day together.
"They started arriving from 8.45am onwards," Ms Starbuck said.
Some came for the school's daily chapel service at 9am, led by grade five students.
Others made the most of the school's annual book fair, which Ms Starbuck said had been going for most of the week, and bought literary gifts for the students.
Ms Starbuck said a morning tea was the highlight of recess.
"Just after recess, there was a concert in the hall," she said.
The year four choir performed, supported by the school's music students.
Ms Starbuck said there were several other performances by students.
But she said the sight she most enjoyed was the look on the children's faces as their grandparents and parents arrived.
"When they saw their grandparents, their eyes lit up. There were big smiles on their faces," she said.
She said family members seemed equally delighted to sit in on classes, or to share a picnic lunch. "It was really great to see," Ms Starbuck said.
