  2 days ago I met Gril that her friend has a crush on me. I walked with her to that.girl and she didnt look any way sympatied about me she just facepalmed and get a bit shy when she saw me.Next day she asked me about my name I decided to tell it. When i came back from school I looked on facebook and they in fact invited me. Today I decided to ask for real whats going on she still says that her friend has crush on me stuff. But still the girl that she was talking about doesnt show any kind of feeling to me.They are propobly 1 year younger than me (Im 17) . So my question is are they just joking or theres something more that I dont noticing. Sorry for my english but its not my native laungage

  I have a trip to Paris planned with my parents, girlfriend and her daughter (9yo). Recently we found out that my father has prostate cancer and will need to undergo radiation treatment. He wont be able to come. Should the rest of us still go? My father has my brother and sister who will be able to support him while we are gone. I am going to feel bad if we go without him but also if we don't go at all. My girlfriend, her daughter, and my mother are really looking forward to the trip and still want to go. Should we not go? My sister is giving my mom a hard time about it. The trip is in a month. Thoughts?
