Why would a cartoon man take a shower in a suitcase?

That's a really strange situation. Maybe it's part of a wacky and imaginative story or a crazy dream sequence.

Maybe he's late for a flight and has to catch it. Or he could be running away from something and the suitcase has his important stuff.

The cartoon man might be sad because the suitcase holds something that reminds him of a past failure or disappointment. Or maybe he's going to a new place alone and is scared and sad about it.

Maybe he's in a hurry to catch a flight or train and has to rush with his luggage.
