Every child misbehaves sometimes - these are some of the reasons why. For NSPCC advice on how to encourage better behaviour see our guide: http://www.nspcc.org.uk/help-and-advice/for-parents-and-carers/guides-for-parents/better-behaviour/better-behaviour_wda90710.html
Equality for all. Kids that are in orphanages rarely get adopted and it's harder for them to get a family and home the older they get since most couples want babies, not older children. What's the difference if it's a gay or lesbian or straight couple trying to adopt kids into LOVING homes? Just ask a kid who's never had a family if it matters to them.
I wish everyone understood this and didn't buy their children bunnies for Easter... I always see them back at the pet store a month or so after... So sad because they can be really sweet companions if only given the right care and love.
