I don't know what to call this

Dad :/

I was telling my dad about a person that was going to Hawaii for their Make A Wish trip... This is how the conversation went:
Me: blah blah Make A Wish blah blah Hawaii (I don't remember exactly what I said😂)
Dad: Now if only you had some awful disease so we could do that...
Me: :/ thanks
Haha ya. Don't worry he was kidding... I think O.o
