Those who cancel on you over and over or are so too busy to meet?
......................................
I had a guy cancel on me over like 4 times after we've been talking for nearly 4 weeks. Every weekend he had something come up at work or some sob stories with family matters. Eventually I had to pull the trigger as it's said.
Even had some who discontinued talking around the times of discussing a meet up like they just go offline. While it doesn't cause me a great deal of issues, it's disappointing and my time is valuable.
I think some people are just clueless to how it disappoints or inconveniences others doing habitual canceling not just last minutes though altogether. Or they just have an issue with over committing more than they can manage.
