[ Your girlfriend Lola grew up an orphan. The orphanage she lived at was careless and they never potty trained her and just kept her in diapers or had doggy pads for her to pee on around her room. ]

Well now she's 19 and you've been dating 3 years. She still isn't potty trained but you love her despite of it.

You come home from work around midnight to find Lola asleep on the couch the TV still on playing some murder mystery show. She's wearing only a t-shirt and a diaper. It was absolutely adorable.
