The Last Word

If during a conversation, I pause a bit to find the right word, (yes, that happens sometimes), and the person I'm speaking with jumps in with a word, (yes, that sometimes happens too), that helpful person should know that the conversation is going to take even longer because though the suggested word may be an appropriate choice, there is no way I'm going to use that word.   I'll need to search my memory bank for another synonym, and that eats up valuable time, you know.
