My best friend and I have the same birthday. My parents are taking us out to an upscale restaurant for dinner and we're staying at a hotel on the beach afterward. My best friend and I have a mutual friend (although neither one of us is close with her). My best friend spoke to her about our plans and asked me if it would be okay if she spent the night at the hotel with us. I like her, so I said that was fine. I told her that I would leave a room key at the front desk for her so she could hang in the hotel while she waited for us to come back from dinner. Earlier tonight, she texted my best friend making comments like "I hope her family doesn't take long to eat/I hope they make dinner quick/I'm sure her parents will take into consideration that I'm waiting and we're all going out after." I didn't invite her to dinner because it is about $75 per person and I'm not going to expect my parents to pay for someone I hardly know and who they've never met. Also, this is a steak house and she's a vegan. Am I in the wrong? Or is she for making us feel like we need to hurry up with dinner so we don't keep her waiting?
