Proper posture is essential when dining.
Sit with a straight back. Lean forward from your hips ever so slightly as you bring your food from your plate to your mouth.
Do not round the back or bring your head down toward the plate to “shovel” your food in to your mouth. The food should come to you.
Also, do not sit in your chair as if you were lounging. Doing so is a guarantee to have food land in your lap.
