So generally while travelling in a metro we come those beautiful ladies like no other. Good physique, Amazing sense of style and fashion,etc. Most of them have either earphones or headphones on or have a intimidating look( that Resting bitch face look) or both or sometimes they are with their friend or friends. So tell me what's the appropriate way to approach and compliment them Because I wanna practice giving compliments with no expectations. Also what amount of complimenting is appropriate?
