Should we remind a person who eats forgetfully that s/he is fasting?

If the person who eats or drinks something forgetfully while fasting is old, ill, weak and not healthy enough to fast, then the one witnessing this should not remind him/her that s/he was fasting. Otherwise, s/he should be reminded (Shurunbuali Maraq al-Falah, 238).
