A while back Lucy started picking small fresh flowers (and occasionally weeds too, but who's to notice) from the garden, putting them in a vase, filling it with water and then sitting it on my bedside table. She would do all this without me around so I would just walk in to find them sitting there. Sometimes she picks daisies but unfortunately I don't have a vase small enough to put them in (a thimble, perhaps?). And if all this wasn't enough I noticed her the other day putting some fresh water in the same vase of flowers she'd picked the day before. I think this act of thoughtfulness is adorable and it amazes me that it's within her at age four.
And just an aside, this is the top image filtered in Photoshop.
