Random Questions and Musings - please reply with answers

So I've been day dreaming a lot lately. On the bus, before bed, etc. I realized that I come up with some really random thoughts and questions about life, so I am going to pose these questions to you and see if anyone has some answers.....

• How come everyone has a favorite colored M&M when they all taste the same?
• What is the difference between being ticked, miffed or pissed and someone?
• How come the guys on my bus have good manners but terrible hygiene?
• Why do RSVPs ask if you have a plus one to bring if the invite doesn't say plus one?
• Why do bowls never quite fit right in the dishwasher?
• Why is everything in llama font automatically amazing?
• When do parents stop treating us like kids?
• How come I can't seem to get off the family plan on verizon?
• At what age should you not have a roommate anymore if you don't live with a significant other?
• McDonalds or Wendy's Fries?
• Why do we try harder to impress strangers than our best friends?
• How come everything has more calories at fastfood places? Normal bagel 250 cal vs mcdonald's bagel 500 cal (not actual numbers).
