Oftentimes, while in the middle of a conversation, there will be a word that I want to use because it fits the context perfectly, and yet I am unable to remember the word.
It hovers there, right on the edge of my consciousness, taunting me. Usually it comes to me a few minutes — or hours — later when I no longer need it.
It would be nice to have a dictionary in my head, but the next best option is to have one on my computer. For this I use Artha.
