Peer pressure... it is perhaps the most popular and oft used word amongst students. When I was in college, More often than not my hosteller classmates would whine and complain about running out of money half way down a month. On the other hand, there were few who would talk about freelancing, interning or taking up tuition classes to support their expenses. It is alright to be clear about your resources and expenditure costs while living away from home and especially when you are a student. So, you can always choose alternatives to spend time with your friends without secluding yourself. As for example, offer for a cheaper food joint with a friendly ambience instead of high-end ones to spend time with your buddies, thereby balancing both sides without compromising.
