How do you tell someone your upset with them but yet you still love them without hurting their feelings?

playfully be real sweet...and in a playful voice be like "im not talkin to yah..why did you have to do....(dot dot dot)" fill in the blanks just show that ur bein playful and than slowly get into a serious tone...than at the end remind them that everything is ok and you still love them...if you don't practice now than how will u gain each others trust
