If my friend did that to my husband…

(Well, it’s not actually a spoiler as it’s no big deal in the show)

When Gaby kisses Tom - wtf?! Why do they all act so chill and so “it-was-just-a-joke”?! Why was Lynette only mildly annoyed?! Okay, sure she was upset but… I would probably stop talking to my friend if she did that!

Am I overreacting, or are they all just… way too open?
