Being a foster parent, for me.
Watched a TV show in which the lady being featured works full-time as a temporary foster parent. Her speciality is taking care of infants/toddlers who cannot live with their original families and have been entrusted to her for the time being - until they have found permanent adoptive families.
There was a scene that showed her bidding farewell to the latest toddler placed in her care. She managed the separation delicately, giving the child finger bumps all the way until the latter went inside the lift. And then, she cried.
I just wanna rush over to my kids and hug them a little harder.
