You're happy to help people out on Monday, but you're not exactly thrilled about your suspicion that people are perhaps taking advantage of you. Is that what's happening? Or are you just being over-sensitive? Friends -- they can be so confusing. Just keep your wits about you, and the moment you feel like someone might be taking you for a ride, call them on it, especially Wednesday. (Nothing commands more respect than just being upfront with people.) On Friday or possibly over the weekend, someone you adore is going to ask you for some help, and you're going to be perfectly happy to do whatever they need.
