HAPPY BIRTHDAY TO YOU. Happy Birthday to you. Happy Birthday to Suzi, Happy Birthday to you. ....and many more!
Happy Birthday! So sorry to hear you're not feeling well.
Just plan to reschedule your birthday outing to another time.
My birthday is the end of January. It's either too cold, or the weather's bad, or someone's sick, so I don't get to celebrate until another time. I can relate.
