It seems like everyone has more disposable income than you have right now, and they're inviting you along to some social events that seem to require greater amounts of it than you are comfortable spending. You're stuck between a rock and a hard place: do you tell them it's too pricey for your budget and make them feel sorry for you? Or do you go along with it and resent the expense? When in doubt, do what is best. They'll understand you, not pity you.
