I really hate it when people play fast and loose with my time. You make a commitment, a suggestion, an agreement, DON'T back out on me at the last minute, or not even the last minute, PAST the appointed time. It's really frustrating for me when people don't respect my time. Here's how it usually goes.
Let's say I have an appointment at 2 pm, I won't schedule or arrange anything that will not give me about an hour contingency time around that appointment, because shit happens, and I hate making people wait.
Here's this weekend: I asked if friends X&Y were going to Costco so I could tag along. X&Y said they would let me know if they were going, but I knew there was going to be a problem. Y tends to have a problem respecting people's time. Unfortunately, despite what it seems, I have things to do! And I can't go out and do them if I'm expecting that at any moment they might call me and say "oh we're going to Costco right now wanna come" and if I'm downtown or whatever then I miss out, right? Frustrating. And particularly because this isn't the first time this is all happening. Anyway, I get a text last night about going to Costco this morning at 11 am. I reply yes when I see it in the morning. Then 11 am rolls around and nothing.. half an hour later, AFTER THE FACT, I get a text saying she's "not feeling well and they won't go today". Thanks. Thanks. Cos you know, my time is so invaluable it doesn't need to be respected. Like I could have run half a dozen errands by now. You make an appointed time, you KEEP it. Plus like I said, she might really not be feeling well, but that's definitely not the first time.
"Oh yes, I'll meet you there at 3 pm"
"Oh sorry, I'm not feeling well"
Over and over again.
