As a shy girl who experienced your same problem, I found that thinking "What would I talk about if I was drunk?" helped me to keep the conversation flowing, because it made me get over trying to have "proper" conversation all the time. Non sequiturs are a good thing when chatting.

I would guess it means 'H' for Harry.

Have you ever worked with a big-name actor or actress who you thought was terrible at their job?
