Why was Greg kind of nervous about going to Grammies house?

This is the house of Gammie, it's very big, old and grand at 38 bacon street.Most of the The Heffley Family Reunion mainly takes place in this house. The house has many pictures and albums of family members. There wasn't anything fun there, so Greg complained to Susan, Susan got Lego blocks. However, Gammie glued them together because she didn't like having little pieces all over. Gammie's furniture has a sticky note with the name of different family members written by the member, this is because when Gammie dies, the members would take the furniture and things. Greg also took some things. There are also many bedrooms in the house, The Bachelors have to sleep in a big room, which has two beds, making four bachelors double up and sleep, while the rest have to sleep with sleeping bags on the floor.
