Here's a little story about a time where Supergirl gets tired of living in an orphanage and resorts to drastic measures in hopes that she can get the hell out of there. It's from Superman's Girlfriend Lois Lane #14 (1960).
So this is how desperate and crazy poor Supergirl has gotten. And here's her plan:
Alright! Way to beat Superman at his own game! This is the sort of crap he would normally be pulling on Lois, because Superman loves nothing more than making Lois think she's crazy. Here's my favourite one:
Also..."Severe Kitchen Ware."
So Superman decides that he might possibly be in love with Lois. Which I never thought was the issue. I thought he just didn't want to put her in danger so he never acted on his feelings. Right?
I'll bet he did.
Good lord! Look at the size of Perry's pleasure schooner! How much does the editor of the Daily Planet make?!
And now it's time for Supergirl to make some romance happen:
What?! No! Ok, look Superman. It's one thing to suddenly decide not to propose to a lady, but you should NOT tell her that you were just about to propose but decided not to because she fell in the water. That's just cold. As is flying away suddenly, leaving Lois alone on a boat.
Superman feels kinda bad the next day, and decides to go apologize:
"Love, Batman." I just melted. I know it's not really him writing that card, but still...
Well, it turns out that Superman was playing along the whole time:
Well, at least not until your next appearance, when Superman makes you pretend to be his fiance. And it is just as creepy as it sounds. But I already talked about that story way back here.
