Surprise parties

I pride myself on being a good friend, but I really shit the bed earlier this year. I had completely forgot my buddy's  birthday- to be fair, it's the day after I received the pay check and I wasn't thinking particularly clearly, but I should have left a note for myself. I apologized profusely, but Tabby kept saying, "No, it's fine! " in that high-pitched "I'm still super pissed" voice, so I know I have to make up for it somehow, and then I had an idea.

Everyone expects a surprise party on their birthday, but how many people get one on their half-birthday? Tabby turns 26 and a half last night. I sms all our friends to meet at our usual spot at Clark Quay. Everyone turned up. When Tabby finally arrived 1 hour late, she was really surprised! She thought it's just a normal gathering for drinks.  And thus began apologizing profusely to each of us for being late to her own 'surprise-half-birthday'.
Weird isn't it?
