. You have to travel alone.

You cannot just hop in your car and reach home. You have to carry your luggage all the way to the airport and get it security checked. There is no body to talk to you in between the travel time. You have to be careful about your luggage. Even if you want to go to the loo on the airport, you have to take your luggage along. You have to eat alone with your luggage. You have to talk to the airport staff and convince them that your luggage is less that the weight allowed on board. 5. homesickness At least once in a month, you feel homesick. There are times, when you feel like running back to home and never come back. You miss your parents, your siblings, your bedroom and your dog. You get jealous of your friends living close to college. You talk to your mom many times on phone and convince yourself that you'll go back home very soon.
