Well I don't think Islam is that rigid as people make it out to be. I recently celebrated my 34th birthday with lots of fanfare.. In fact I had two bithday parties.. First with my close gal friends and second with family so I cut two cakes for one birthday. I love celebrating my birthday everyyear. In fact many people ridicule me saying I am too old to cut cakes and stuff but I say what the heck.. This one day is just mine and I am the most important person on that day.. People start wishing me at midnight and get so many presents.. Birthdays are fun. I am sure celebrating anniversaries are allowed as well for those who are happily married that is..
