ものですから・もので

This grammar is used to give a justification or explanation for your actions or a situation, often with a soft or polite tone. It emphasizes the speaker’s circumstances as the reason. ものですから is a more explicit, spoken justification; もので is a bit softer and can appear in slightly less direct contexts. Use when you want to explain why something happened or why you’re taking a certain action, especially in conversations with others or in formal-ish situations.
