Building a Bayis Neeman B'Yisrael Q&A - The Little Things

This week's Question - Most of the times I find myself struggling with Shalom Bayis it is with the "little things", when I become frustrated with my husband about disagreement of timing or general miscommunications. I find it hard to remain calm and speak nicely and kindly when I find the miscommunications very upsetting. What is your advice to help this?
