Stepdaughter Lists Me as Her Mother

Yesterday on Facebook, my stepdaughter updated her info page to include her parents.  She listed her dad as her father (duh!), her mother as her mother (duh!) and me as her mother (surprise!).  I was surprised but pleasantly so.  I am not sure what her mother will think of that.  I'm not sure if she has access to it or not (she isn't on my stepdaughter's friend list which I find a bit odd).  At almost 18, the ex may not have her log-in information either. 

It was nice to see that the decade we were so close wasn't forgotten but at the same time, I hope it doesn't give her mom a reason to resent me again when the two homes are communicating in a friendly manner now.  I never told the kids they had to call me mom.  It was always left up to them - always, always, always - what they wanted to call me (as long as it wasn't a bad word:).
