People (ex's mother,sisters) who do the absolute LEAST (they don't visit, send ANYthing and expect *me* to call *them* so they could converse with the kids) really "expect" me to just up and send them/do anything in regards to my children. They're basically complete strangers. The "most" they do, is ask about the kids (and even THAT'S rare!)

Mind you, have have zeroe problems with the father side of the family wanting to be part of their lives but I shouldn't be the one making sure they do their part. The same way I shouldn't have to make a grown man do his part in helping either.
