PIL and us were invited to the garden party of MIL’s relatives. We were six altogether so wouldn’t fit in a normal car. Instead of taking two cars for the an hour and half drive MIL suggested that I go to spa for the day and the rest go there in one car. Dc were 4 and 6. Little bit odd I thought and said I am not interested in spa so I come to the party. They rent a seven seater but I felt PIL were annoyed.
