Whether your mom should have told you that she had 5 of her female friends over depends on the specific circumstances and dynamics of your family. Here are some considerations to keep in mind:
Open communication: In families with open and transparent communication, it is common for parents to inform their children about events happening at home. Sharing such information fosters trust and allows family members to be aware of each other's plans and activities.
Personal boundaries: On the other hand, everyone has different boundaries when it comes to privacy and personal space. Some people prefer more privacy and may not feel the need to share every detail of their social activities, while others appreciate being kept informed.
Age and independence: Your age and level of independence may also play a role. Younger children may need more communication from their parents regarding activities happening in the household, while older children and adults may require less involvement in their parents' social plans.
House rules: Consider whether there are established house rules or expectations regarding informing each other about visitors or social gatherings.
Respect and consideration: Regardless of the specific situation, it is essential for family members to treat each other with respect and consideration. If your mom's decision not to inform you about her friends visiting made you feel excluded or upset, it might be worth discussing your feelings with her.
Understanding the reasons: Try to understand your mom's perspective as well. Perhaps she didn't think it would be a big deal or assumed you were busy with other things at the time.
In general, healthy family relationships involve open communication, respect for each other's boundaries, and consideration for each family member's feelings. If you feel strongly about wanting to be informed about such gatherings in the future, consider having a calm and non-confrontational conversation with your mom about your preferences and feelings. This can lead to a better understanding between you both and improve communication within the family.
