"Ugh, shut up. You love to woo," Lily retorted, though turned her head away in slight embarrassment. Maybe the woo noise was only for single people. Was her woo not genuine because she had a ring on her finger? Despite Marshall's absence, Lily was still married.
Honestly though, Lily thought the woo was for people facing struggles in their lives. If being in Marrowood wasn't a struggle, then she didn't know what was. Then there was the fact that her husband was missing. Lisa was also having romantic woes and Robin was too, even if she thought everything was going well with Ted. They would eventually break up and she wasn't looking forward to that. Again.
