Hello, everyone:

May I ask if there is any significant difference in the sentences below? Thank you!

Mary tells her mother (that) she won't come for dinner and (she) goes shopping with her friends.

Mary tells her mother (that) she won't come for dinner and that (she) goes shopping with her friends.

 In the first, Mary does two things: 1) she tells her mother something, and 2)she goes out shopping.
In the second, Mary tells her mother two things. However, the second is not grammatical.
Mary tells her mother that she won't come home for dinner and that she is going shopping.
