L comes to you and tells you he's getting married. He wants you to help him pick out a tux. What is your reaction?
Personally, I'd grill him about this person he's marrying. Who is she? Is she understanding enough? Is she kind enough? I'm protective of my friends and I'd totally shred her if I didn't think she was good enough for my buddy and ex-boyfriend, L.
Unless it was Light. Then I'd say "WHAT THE HELL TOOK YOU GUYS SO LONG??? You'd look good in blue and yellow. The tux being black, and all." (XD)
