Why Do I Do This To Myself?

So my mom and I went to Cheesecake Factory for dinner.  Super yum!  Then we decided to walk around the mall a bit before going and getting dessert on the way home.  We passed Pottery Barn Kids and one of the pictures in the window (the ones that show you "real" kids using the products to entice you to go in) had a kid using a turtle towel (even though it was wrapped around the kid, I could tell it had turtles on it!).  We went in so I could buy the turtle towel.  Turns out they have a WHOLE LINE of turtle stuff right now. Well, my mom being who she is went a bit crazy and picked up every single turtle item there was.  That included kids toys, kids plates and cups, baby feeding set, rattle, crib sheets, blanket, tote, lunchbox, stuffed animal, lovies, nightlight, pillow, soap dish (the rest of the set wasn't turtles), and the towel we originally went in for.  I started to get upset since the guy helping my mom assumed it was all for me and that I was pregnant because he was advising when to use the different items after the baby was born.
Then when we left my mom wasn't thinking and said we have all the baby stuff and now all I need is a baby.  As soon as she said it she got upset at herself and realized what she said and apologized.  I know she didn't mean to hurt me and didn't realize what she was saying.  However, that doesn't make it hurt less.
