My SO is like having another child

My SO is starting a new job and needs to get business casual work clothes. He went shopping today but because our little girl is sick I stayed home. He was gone for nearly 3 hours. When he walked through the door he slammed it and said " I'm never going shopping without you again, I don't know what matches and it's just too hard". He didn't buy one single thing. I thought his little tantrum was adorable and couldn't help but laugh. Ladies tell me something you SO does that is child like. But you love them for it.
