To those people who make plans and then cancel on you at the last minute

You're really inconsiderate.

Knowing that we have already agreed to fork out time and that time is reserved to let's say have a meal together, and that prohibits me from making other plans. Do you not realise that i've worked my schedule around meeting up with you? And perhaps on the day before our supposed meet-up, you decide to flake out just because you want to sleep in/watch your favourite TV series/you don't feel like you're up to it/whatever excuses you come up with.

 

Do you think it's really fair? 

Of course I wouldn't mind if you've a reasonable excuse like something urgent you've to attend to e.g.  visiting a family member at the hospital. But other than that, you're just being really selfish when the other party has already invested time to making these plans which they look forward to, just to have you bail out on them with a crappy excuse. 

The most you can do is give an early notice that you won't be able to make it and postpone the plans. Ensure you have plenty of rest the day before and please just honour people's invitations.
