There could be several reasons why people may not show up for appointments or fail to notify others when they can’t make it. Some common reasons include:

Forgetfulness: In today’s fast-paced world, people often have busy schedules and may simply forget about appointments they have made.
Lack of prioritization: Some individuals may not prioritize keeping appointments or may not see the importance of showing up on time.
Communication issues: People might face communication barriers that prevent them from contacting others to cancel or reschedule appointments. This could be due to a lack of access to communication tools or difficulties in expressing themselves.
Fear or anxiety: Some individuals may experience anxiety or fear about attending appointments, leading them to avoid or cancel them without informing the other party.
Lack of respect for others’ time: In some cases, individuals may not value or respect other people’s time, leading them to be careless about keeping appointments.
Overbooking or double-booking: Sometimes people may overbook themselves or double-book appointments, leading to conflicts and resulting in missed appointments.
It’s essential for individuals to be mindful of the commitments they make and to communicate effectively if they are unable to keep an appointment. Notifying the other party in advance allows for rescheduling or making alternative arrangements, which shows respect for the time and effort of others.
