I find visual or audio stimulus can wear me out! I was trying to talk to this nice 93 year old man at the church bean supper, and between the heat, the noise, and the people buzzing, I was losing it. Poor thing looked at me and said "am I spitting on you dear?" and I realized that EVERY word that came out of his mouth was making me flinch! I was so embarrassed. I told him I was in sensory stimulus overload, and apologized. He wanted to help me to a chair. How sweet is that?
