With Mercury in Taurus, if something interests them, they usually speak clearly and directly. If it does not catch their attention, they may dodge the subject or stay silent. They value their time and prefer a conversation to get to the point without too much going around in circles.
They commit to what they say and find it hard to change their mind. They may press a question until they get an answer. In the same way, if you ask them something again in the hope that they have changed their mind, they will probably stand by their earlier answer.
They need time to understand new information and to make decisions. They like to organize in their mind what they will do before leaving home, so a change of plans is easier to accept if it is announced in advance.
They may be slow to commit, but once they do, they place great value on their word. In matters of the heart, they tend to feel more than they express and do not always find it necessary to turn every feeling into a declaration.
