I personally think that it’s fine to apologise as you made your partner wait, not knowing what happened. But, not necessarily a deep apology, rather, a polite way of excusing yourself for falling a sleep. Not much of a big deal, I’d say.
EVERYONE!!! always remember na hindi mali ang makatulog while talking with your s/o or sino pa man yan kasi una sa lahat TAO KA and NAPAPAGOD ka rin physically SO NEVER SAY SORRY FOR FALLING ASLEEP. hindi mali yun 😌🫴
