So I did go to Ben Franklin today. I was in the framing department, looking through some mats. DS3 was talking loudly and grabbing at the frames, so I just kept talking to him quietly and trying to keep him from damaging anything.
One of the clerks says something like, "Oh, honey, are you helping Grandma pick out some mats?" and she smiles at me.
I smile back and say, "I'm his mother, actually." She looks about my age, so I'm guessing she's got older kids...
She says, "Oh, I thought I heard him call you 'Grandma'." I didn't say anything further; it's possible, I suppose 'Mama' sounds like 'Grandma'.
Then a co-worker comes up to her and commiserates with her on her faux pas. "It's so hard to tell sometimes. The worst is when you ask someone when they're due and they say they aren't pregnant! I've learned not to say anything anymore."
I'm standing there thumbing through the mats thinking, "I am still right here, folks!" Good call on not saying anything at all, I say. If you don't know, don't assume. Shut up! GEESH!
