Mom asking “did you eat?” for the fifth time is affection with a limited vocabulary. Answer nicely.
GRATITUDE
GRATITUDE
Plenty of people care in a language with only a few words in it. The question about food is not about food, and asking it five times is not forgetfulness; it is the available phrase for wanting to know you are all right. The content is thin and the feeling behind it is not.
Answer properly rather than with a grunt, and give one extra detail about what you actually ate. Then try answering the real question once: say that you are fine, or that you are not. If you want to go further, ask her the same thing, since nobody asks the one doing the asking.
Which repeated question from your family is really affection?
Free, with nothing to buy inside it.
