Happy Father's Day in Poland today...how is the holiday celebrated there?

Not as much as Mother's Day. It is after the Mother's Day and Child's Day and after the end of school year. In schools it is sometimes celebrated together with the school year. In Poland a lot of people feel that mothers are more caring and hard-working parents than fathers, so they deserve more attention on their special day. But fathers do get attention too, usually in form of small gifts. This year we gave our Dad plums in chocolate (his favorite sweets) and a 3D card. He had forgotten about the fathers day so we took him by total suprise ;).
