You make an excellant point, Lord Sura!!!! Hopefully one of these inappreciative individuals will read this post and realize what they're doing really isn't cool.
Hahahaha xD I have a hard time saying no myself and normally just adopt them... :3 However, I act like the most terrible mother ever. For ex. Ignoring them, running off and leaving them, "Forgetting" To feed and take care of them... Eventually they get tired of it and go away xD
