752, red eye, 5 hours delay, My seat 1F, after boarding dude asked me to move to 1A so that he can sit with his newly wed wife.
I knew that 1A will be affected by galley light all night, so I politely asked him to ask the lady in 1B to move to 1E, so that he can sit with his wife in 1A&B.

1B accepted and everyone was happy
I felt like I did a favor for 1B, as well as the couple!
