AITA For Leaving My Roommate’s Kid Alone After Saying I Couldn’t Babysit?

A frantic dash to the office turned into a roommate showdown when a 25-year-old woman left her apartment, unaware her roommate’s 7-year-old daughter was home alone. The roommate, expecting her to “just be present” after she explicitly declined to babysit, unleashed his anger, accusing her of negligence. Caught between work chaos and an unasked responsibility, the OP stood her ground, insisting she’s not a stand-in parent.

This AITA post unpacks a tense clash over boundaries, assumptions, and childcare. Reddit’s firmly in the OP’s corner, but was she careless, or was the roommate out of line? Let’s dive into this domestic drama, where duty and denial collide.

‘AITA For Leaving My Roommate’s Kid Alone After Saying I Couldn’t Babysit?’

An urgent work call and a roommate’s misplaced trust led to a heated confrontation over a child left alone. Here’s the Reddit user’s story in their own words:

This roommate rift highlights the dangers of unclear communication and misplaced expectations in shared living spaces. The OP’s refusal to babysit was clear, yet the roommate’s assumption that her presence equaled consent created a risky situation for his daughter. His failure to confirm her role before leaving suggests an attempt to offload responsibility, a move that backfired.

Dr. Harriet Lerner, a relationship expert, notes, “Assumptions in relationships, especially around responsibilities, breed resentment when unspoken expectations aren’t met” (Source). The roommate’s insistence that “just being present” isn’t babysitting ignores the legal and ethical weight of leaving a 7-year-old unsupervised. A 2023 Journal of Community Psychology study found that 45% of roommate conflicts stem from unaddressed assumptions about shared duties (Source).

This ties to broader issues of parental responsibility and roommate dynamics. The OP’s focus on work under pressure was reasonable, but noticing the child alone could have prompted a quick check. Advice: OP should firmly tell the roommate, “I can’t take on childcare; please arrange reliable sitters.”

She could document this in writing to avoid future disputes. Moving out, as planned, is wise, and a mediator or landlord might help enforce boundaries until then. If the roommate repeats this, contacting child protective services, as some Redditors suggest, could be a last resort.

Here’s the comments of Reddit users:
