@WashedOutGundamPilot@StoleMyThundersBalls Gary's right about the pastel color thing. Lego did the same thing for girls, my sister had a house set. She built the set, disassembled it, and it got absorbed into my large Lego bucket, as she move on to different toys.
Girls are just different, and we should not expect to find one to tick like us. Hard lesson for me. Exceptions truly are unicorns. Those girls won't be attracted by pastels.
