Today I noticed one of my potted plants hanging off of the shelf where it normally sits. This usually means the baby got to it - she puts her feet on the bottom shelf and hoists herself up. Usually this section of the room is off-limits for this reason. The pot was nowhere to be found. Definitely the baby. As I went to fix it I noticed it was basically on the verge of death so I asked my SO if she knew it was like that.

Her: What plant?

Me: This plant

Her: Oh yeah, it's been that way for a week *shrugs*

*Note: I've been away on business and only recently returned home*

Me: (frustrated) Thanks. You could have said something about it, it's basically dead at this point

Her: How is this MY fault!? I didn't know it shouldn't be like that!

Me: How could you not know a plant shouldn't be hanging from a shelf without a pot? And when you found a random plant pot on the ground, saw a plant hanging off the shelf, and didn't either think that's not normal or to at least say anything to me? Also why was the baby left unattended (again!) long enough that she was able to climb up there, de-pot a plant, and then run around with the glass pot, also unattended? And you saw all of this and never thought anything was strange about it?

Her: Well I didn't know the plant needed a pot. I've only seen it once before this (when it was in a pot, on the shelf, like all the other plants)

It's worth mentioning that she has plenty of her own house plants - it's not just a me-only hobby that she's clueless about.

Who's TA here?
