Quick question for you guys. This mostly pertains to when there is some sort of a significant age difference (5+ yrs) between the two of you..

When age comes up and a girl asks you to guess their age. How do you respond? Are you honest and tell them how old you think they are, or do you shoot for 3-5 years younger (with an older woman) to make them feel good, or do you have a Go-To line?
