text: is it wrong to kiss a guy and not tell your friend about it? because one of my friends heard it from someone else and now she says that i lied to her and she is mad at me. kissing is a personal thing that is between you and the one you kissed. if you denyed it, i could see her being mad,but if you said nothing (to anyone) i do not see a problem. if you had told others and not her,then she would feel let down. you are not required to tell your friend everything. even if she tells you. do tell her why you had not mentioned it though. like you were thinking of your feelings after the kiss and trying to decide if it was worth talking about. she most likely feels since others knew that you don't find her opinion worthy of notice. reassure her that was not a factor.
