AITA for telling my little bro he can’t come grocery shopping with me unless he starts being more hygienic?

Teenagers often go through phases where personal hygiene takes a back seat to other interests or simple laziness. Most families deal with it through gentle reminders, but sometimes those reminders aren’t enough, and the issue starts affecting everyone around them.

One 20-year-old sister recently reached her limit with her 16-year-old brother’s extreme lack of hygiene. After months of subtle hints, direct conversations, and even buying him deodorant, she decided to set a firm boundary: no more grocery shopping trips together unless he steps up his routine. The decision sparked a big reaction, leaving her wondering if she went too far.

‘AITA for telling my little bro he can’t come grocery shopping with me unless he starts being more hygienic?’

The post begins with background on the brother’s hygiene habits and how the family has tried to address them over time.

The situation escalated when the brother wanted to join grocery shopping, leading to the sister’s boundary.

The poster reflects on her feelings and the bigger picture of responsibility at his age.

This conflict centers on a teenager’s resistance to basic hygiene clashing with family members’ need for comfort in shared spaces. The sister set a reasonable boundary after repeated failed attempts to encourage change. The brother’s reaction shows typical teen pushback, but his excuses reveal a mix of defiance and possible unawareness of how others perceive him.

Underlying causes could include depression, low self-esteem, or simply teenage rebellion against authority. Parents’ enabling (washing his clothes, not enforcing rules) may contribute to the behavior continuing. The sister’s embarrassment in public is valid — hygiene affects everyone nearby.

Adolescent psychologist Dr. Laurence Steinberg has noted that “Teens often test limits to establish independence, but consistent, calm boundaries help them learn responsibility without resentment.” Here, the sister’s consequence was logical and tied directly to the issue.

The family could benefit from a calm group talk, possibly involving a neutral third party like a counselor if depression is suspected. Parents should step up with clear rules about hygiene as a non-negotiable. The sister can continue her boundary while offering support — perhaps shopping together once he shows effort. Small steps and empathy usually work better than shame in the long run.

Here’s the input from the Reddit crowd:

The online community overwhelmingly supported the original poster, agreeing that basic hygiene is non-negotiable at 16 and praising her for setting a fair boundary.

Most readers viewed the brother’s behavior as unacceptable and placed responsibility on him (and parents) rather than the sister:

Many pointed to possible depression or rebellion and shared similar family experiences:

A few added humor or strong opinions about consequences and parental enabling:

This situation highlights how teenage rebellion or laziness around hygiene can strain family relationships and public comfort. Setting clear boundaries shows care, even if it feels harsh in the moment. With time, most teens outgrow these phases when they face real consequences or start caring about how others see them.
