Parenting: It takes two to tango.

When I was thinking about the definition of the word “tandem”, where several similar elements work in one mechanism, located on the same axis and the work of one is impossible without the other, and also means the union and joint activity, I thought about parenting…
I am a mother and it seems to me that the child’s parents are a wonderful tandem, where everyone’s role is important. But the parental share is not easy, and I added a little humor.
By the way, what other tandems do you see in my illustration?
