Mercury joined the Sun, Jupiter, Saturn, and Pluto in Capricorn yesterday. This will slow communications.
I don't like mental plodding any more than you do, but there's a reason for everything and always something to learn.
With Mercury in Capricorn, give people time to respond. It's the mature thing to do. It demonstrates you have something precious - boundaries.
The boundary is not merely about resisting the urge to push or rush someone. You might realize that your timing and your way of communicating is unique to you. You can think of it as being "defined". With that settled, you realize the other person is in a similar circumstance.
A number of years ago, I was having trouble understanding my son. It was bad enough that I went for a hearing evaluation. I saw a specialist who performed a battery of tests.
It turned out I had no problem or hearing loss at all. The doctor told me to go home and tell my son to quit mumbling and talking so fast that he could not be understood. "Tell him: Communication is a two-way street!"
Mercury will be in Capricorn for about three weeks. Work with it, and you'll enjoy a lasting benefit.
