Dear Ann!
Great party of yours, yesterday I had a great fun. And I'm really sorry I had to leave your birthday party earlier, I didn't mean to offend you. My brother, Adam called me during the party and told me that our Mom has been transported to the st. Mary's Hospital. She has had a heart attack but luckily my brother was a room far from her. In a moment he called an ambulance and went to the hospital with her, then he called me. I had to come back to home and take care of our little sister, Katie. I was thorn apart that i had to spoil your birthday surprise we made with Clara and Maya. Still I hope your birthday party was great. Next time I will try to stay until the very end.
Please accept my apologies
