My coworker who I have some interpersonal difficulties with told me I wasn't annoying and am a very sweet person. That made me feel good. I had to ask her for help yesterday and Friday (although she denied me the help on Friday) and so I sent her a thank you Starbucks card to her email yesterday to thank her for the help. She said that was nice but wasn't necessary. I just told her that I like to make sure that people know that I appreciate their kindnesses.
