[This is a problem that's pretty unique to Eevees but Susie will try to Team Mom her way through this. It's not your fault you evolved. I'm sure she understands that.]

W-well yeah, but it's still not nice to do things that'll make people cry.

[Shaun's entire life for the past few years (this past year in Johto the exception) has been nothing but tears. He could go the rest of his life without seeing anyone else cry and there would still be too many tears in his life.]

How would you like it if someone pretended to take something of yours and you didn't know they were joking?
