I really like it.
Children always think you can do anything and that you're always your best self.
It's what I imagine being a grandparent is like. You're only there to spoil them and do the fun things and then boom, back to their mom and dad. Not that parenting is something I don't want to do, it's just something as an uncle you don't sign up for.
I love it. It's the next best thing to having children.
Whenever they see you, they're usually happy because you're seen as an authority but not a disciplinarian.
As materialistic as people say I am (I'm gay, I don't have kids, I like my comforts) it really is so sweet buying gifts for them and seeing them react. Don't beat yourself up if you watch videos and think that's stupid...it really has to be "your" kids. However they are yours.
I have plenty of their drawings on my fridge. It's very cute. I never figured myself for that type of person primarily because I had to talk myself out of it being that kids weren't foreseeable in my future. But it's very sweet. Their faces light up when they see you and they run toward you.
All in all, it made me realize how selfish parents are. Having kids is really all about the parents. LOL
