Words

I have had the hardest time coming up with words lately. Usually this happens when I get tired but yesterday I couldn't think of the right words for things most of the day. When I get stuck, my husband will ask me "what does it do?" "what do you use it for?" or "what does it look like?" -- which doesn't help at all -- it just makes me more frustrated. I was on the phone last night with my son and couldn't remember some words and it is even harder for me when I am on the phone because I know the person can't see me struggling to find the words. A lot of times, I just have to quit talking and come back later to it -- if I remember!
