Being seasick at sea is not the same as being homesick at home.
Being seasick at sea and being homesick at home are fundamentally different experiences. Seasickness is a physical reaction to the movement of the sea, often causing nausea and discomfort, whereas homesickness is an emotional longing for the familiar comfort of home.
The quote by Miriam Toews highlights the distinct nature of these feelings, suggesting that physical discomfort from the sea is not comparable to the emotional ache of missing one's home. Both can be challenging, but they stem from different causes and evoke different responses.
