What she did was retarded, whether she thought you guys were gay or not. It's a fucking sundae. It's not shareable. If one person orders the sundae, one person should get the utensil to fucking eat it. Then, it's up to the other person to request another utensil or not. If you order a strawberry lemonade at the cheesecake factory and your friend doesn't, should you get two straws? No. So, no two spoons for a fucking sundae.
I understand why some people are annoyed by the thread - such as that you actually got mad at her for "thinking you're gay", if that's even the case. But, let's not try to rationalize getting two spoons to share a sundae without asking for two spoons.
I wish this would happen to me so I could punk the shit out of someone.
