Do you always feel gratitude when expressing thanksgiving? via /r/gratitude

Sure I’ll say thanks for small or large gestures or pleasures when I remember or when writing in my gratitude journal. Even everyday occurrences I’ll give thanks for such as purchasing a coffee, clean water, having a roof over my head but I do not think I have a feeling in my heart when I verbally or mentally express my gratitude. Is that normal or do you have a feeling when you say thanks?
