I know this is very silly, but for some reason it annoys me a lot. I am not one to put loads of showoffy pics on Facebook, but every now and then will put on a pic of the family if we have done something special or if it's a birthday etc. I always like everything SIL puts on regardless of what it is just because she is my family and it's nice to see what they are up to. So why does she never like anything DH or I put on despite sometimes saying she saw the pics on Facebook and going on Facebook a lot so she will have seen our stuff. She always likes other family members stuff! We don't see much of her as she lives a few hours away and DH's family are not very close.
