Messaging to cancel a plan

"When was the last time you cancelled a plan? Why did you cancel?"
umm, I don't really remember. But I think it was around a month ago. It's not really canceling a meeting. I need to choose one between two plans. My boyfriend asked me to go to a concert, while my friend asked me to see a musical. In the end, I went to the concert with my boyfriend.

I dont remember this moment,but last time I made a deal to meet in Sunday evening with my friend and she must write me,but she doesnt write.

Last time I had to cancel a plan due to conflicting meetings. I had to choose which one to attend and which to cancel.

When was the last time you canceled a plan? Why did you cancel?
I was supposed to finish one new technology in my field by two weeks later but my laptop broke down so that its windows wouldn't turn on. I was forced to take it to a hardware repairman. after two days he told me he did never encounter this kind of problem and asked me for more time in order that he repaired it. As a result, this happening forced me to set my plan back.
at first, I was very angry because little did I dream that I haven't lived up with my hopes. It was beyond believe for me! why did it occur now?
I was doing my best and put my heart into my job for the last 6 months.
but a little later, I would feel unhappy and try to face this situation more reasonably. I accepted not to try to control uncontrolled circumstances and let me see what would happen.

I'm so sad, i can't come to meeting tomorrow. Because my parents don't letting me.

I canceled my appointment of the clinic because there was an emergency matter before the coming day of the appointment. I didn't want to call off any appointments as usual but sometimes, something is more crucial unexpectedly.

I don't remember when was the last time I cancelled a plan and I don't remember when was the last time I was ill

I cancelled the hotel booking room when my sister fell down last month. She's broken her bone. So I texted to the agent and we didn't have our holiday then.

Nice thing you asked! Just last week I was suppossed to attend a language class but I couldn't make it, I had a terrible cold and awful migraine, To make matter worse my pre schooler was at home all day since there was no school, had to look after her while I was sick. It was such a shame, I missed the class. Fortunately I got better just 2days after and was able to catch up with the missed lessons.

I don't think I can make it to class tomorrow.

*Oh! Poor you! Have you been to the doctor?

Nope, I think Its just a seasonal flu, I have runny stuffy nose and scratchy throat.

*Oooh! sorry to hear that! Pop me a mssg if you need anything!!

Actually, If you don't mind, could you get me an over the counter flu medicine.

* No problem, I'll pick up some meds and drop it off at your house on my way home. See you around 5 then

Thanks, You're a life saver!

* Get plenty of rest! Hope you feel better soon.

I cancelled the trip plan to the beach last 2 month ago. Actually one of my friends made this plan for saying good bye and get relaxing and refreshing for me. I love staying beach a lot so she arranged for us but I can't emphasis and I think I wasn't happy if I didn't get a new job first. That's why I said my friend to cancel our trip.
