While I agree that it's important to make sure you get all your questions answered, you also want to be careful not to grill the sister rushing you. Firing off question after question might make it sound like you have some kind of mental checklist or something. Definitely be genuinely interested in the answer and discuss it a decent amount before you shoot off another question. However, when I rush girls, I ALWAYS ask them if they have any questions that weren't covered during that round/by other girls who've rushed her - especially if they seem shy and might be scared to ask - and I appreciate the girls who do ask questions because it really does make you sound interested in the house.
