Smells like WHAT?

Ellie has so far not said much that would prove to be too embarrassing in public, but I get the feeling that's about to change. The constant commentary in public bathrooms is pretty normal for a three-year old and is usually pretty innocuous. Lines like "Mommy, what's that lady doing? Is she peeing? Why?" even get an anonymous chuckle from the next stall once in a while. However, she has been starting to come up with things out of the blue - you never know whether she's playing with sounds or if she actually heard the word somewhere and just has no idea what it means. Yesterday's line - thankfully uttered at home with just the two of us - was "Mommy, that smells like weed." Um, excuse me? I wasn't sure I heard her right - maybe she meant "wheat," or her friend named Reed, but it sure sounded like "weed." And no, we have not been doing family tours of the dorms lately, or visiting the reputable "medical" establishment that just opened two doors down from church. She weeds the garden with us occasionally, and that's the only association she has for that word, so I am completely mystified. I'm just praying she doesn't feel compelled to share her olfactory findings with a wider audience. Like in the middle of church.
