While I can understand that being asked to clean boogers off the wall may not be the most pleasant task, it's important to remember that expectations around household chores and responsibilities can vary between families. It's difficult for me to say whether it is normal or not, as norms and expectations can differ from household to household.
In situations like this, it's generally advisable to communicate openly with your family members to understand their expectations and discuss any concerns you may have. Here are a few steps you can take in such a situation:
Calmly express your concerns: If you feel uncomfortable or have questions about the task assigned to you, calmly express your feelings to your mom. Explain why you feel uncomfortable or ask for clarification on the reasoning behind the request.
Seek a compromise: Try to find a middle ground that both parties can agree upon. Perhaps there is an alternative chore that you could complete instead of cleaning the boogers off the wall. By suggesting alternatives or compromises, you may be able to reach a more agreeable solution.
Discuss responsibilities: Engage in an open conversation about household responsibilities and how they are shared. This can help set clear expectations and ensure that everyone understands their role in maintaining the cleanliness and upkeep of the home.
Take initiative: Show responsibility by taking the initiative to clean up after yourself and maintain a tidy living space. By doing so, you can demonstrate that you are capable and willing to contribute to the household chores without being explicitly asked.
Remember that family dynamics and expectations can vary, and it's important to maintain open lines of communication and mutual understanding within your family.
