Dear Gloria,

I wonder whether the sentence, "Your manner of thinking and expecting do make their mark." is correct.

I do not tell you that the way I suggest is fail-safe. The realization of your fears will likely not be erased from the face of the Earth. Your car may still break down. It can rain on your parade. Loved ones may leave. At the same time, with your well-being in mind, I maintain that an uplifting and refreshing point of view will uplift your life as you live it. Your manner of thinking and expecting do make their mark. They have as much of an influence on your life as all the thoughts of fearing the worst. Come, look forward to that which you desire coming true.

Your manner is singular, so how can it become plural?

Blessings,
Luus
