Ok now I'm just annoyed.

So recently Chris and I posted a bunch of stuff on Kijiji (Canadian site where you can post free classifieds to buy & sell locally). We have actually done really well and have made almost $500 on stuff we have sold, which I am really proud of.
Anyways, recently I posted a LuLu Lemon hoodie that is too small for me. I received a  reply rather quickly from a very nice lady. She emailed me and quickly explained that she had just fostered a young girl who came to her with only the clothes on her back and she was looking for some nice clothing for her sizes xsmall and small. She continued to say that not only did the girl have nothing of her own but she has never owned anything name brand and so she wanted to purchase the sweater for her.
Of course I instantly was touched by this story. It almost seemed like a sign. I just recently cleaned out my closet which resulted in 2 large bags full of clothes sizes XS and S that I was going to donate. I quickly emailed the lady back explaining this and told her the young girl could gladly have the clothes. There are actually quite a few name brand items in the bags as well. The lady replied to me full of thanks and assured me she would be by on Sunday to pick everything up and buy the hoodie.
Well, Sunday came and Sunday went. I tried e-mailing her a bunch of times but never heard back from her…until last night. She finally replied explaining that she had a family emergency come up and unfortunately wasn’t able to find the time to email me. She said sorry a million times and asked if she could come by tomorrow (which is today) to pick the clothes up. Of course I accepted her apology and told her it was not a  problem.
Well…. it’s tonight. She said she would be here at 5:15 it is now 7:30! I emailed her once again around 6:00 asking if she was still planning on coming by, as I was debating weather to start cooking dinner or not. I have the two bags of clothes and the LuLu hoodie waiting and ready to go at the front door. I was so excited about brightening up a young girls day with some of my unwanted items of cloths. So much better then just donating them to the Salvation Army.
However I don’t know what to think now. This simple sale has become so frustrating. I have turned down 4 other potential buyers waiting on this woman. I am trying to stay optimistic but seriously… once is forgivable but twice…. really?!
