Just strike up a conversation with an in-law and allow them to talk about themselves/their son (they love this although it can be painful). This will be the fastest way to build a relationship with them and once this has happened you will be able to have a friend-ish relationship!
The relationship between the families of inlaws is similar to the relation ship with their family members. For example The relationship of my brother in law(sister's husband) and my another brother in law (wife's brother) will be simmilar to those relation ships with their brother's family.
