The mood shift in this sentence is a shift from a positive, open-ended suggestion (going to the mall) to a more hesitant or unsure question (shopping online). To correct this mood shift, we could rephrase the sentence to maintain the positive tone throughout. For example, "We could go to the mall or explore some online shopping options - what do you think?" This rephrased sentence maintains the positive and open-ended suggestion while still offering the alternative of online shopping. By phrasing it as a question at the end, it invites the listener to consider both options without detracting from the initial suggestion of going to the mall.
