I have always been ambivalent about my birthdays. No, that's not correct; let me rephrase that... I started to become ambivalent when I discovered birthdays weren't just the one day in the year when dad gave us money to splurge big-time on chocolates, pasties and other goodies. That would mean my ambivalence started at about the age of 16 (What can I say? I'm a late bloomer).
Anyway, since then, my birthdays have been days I look forward to on one hand, and wish were non-existent, on the other hand.
I think the best way to show this ambivalence would be to highlight four major things I like about birthdays and another four I dislike about them. And, believe me, nothing spells ambivalence more than the same items appearing in both segments; so, here goes:
The Likes:
1. A Landmark: Birthdays are landmarks. They mark the end of a year and the beginning of a new one. It's definitely a time to take stock and then move on.

3. Contact from 'Friends' I Haven't Been in Touch with for Months (12 Months to Be Exact): Birthdays are days when many people suddenly remember you exist. It is kind of nice when passive or semi-active 'friends' become active for just one day.
4. The Gifts: This is not just material gifts (though I have to say that giant teddy bear I requested is still important *wink*), it's the prayers, the wishes, the texts, the calls (even the missed ones, aka 'flashing'), the Facebook messages and posts, et cetera.
The Dislikes:
1. The Pressure to Celebrate: There is definitely pressure to celebrate birthdays. Sometimes I just want to stay home and celebrate by having a quiet uneventful time, but staying home alone is somehow considered an anomaly.

2. Those Corny Birthday Phrases: Yep, I do have a love/hate relationship with this one. Even though I use them myself and appreciate that they are used as fillers, they do get old sometimes, don't they?
3. Contact from 'Friends' I Haven't Been in Touch with in Months: This is another one of those ones I love and hate. Sometimes I think I'd rather have these fair-birthday friends (Get it? Fair-weather, fair-birthday?) either contact me at least one other time in the year or just not even contact me at all.
4. Friends Forgetting My Birthday: Yeah, I mean even with Facebook reminders and all, some people that I would count as friends still somehow forget my birthday, there are others who wish me happy birthday a day before the date or even a month later without acknowledging or maybe not even realising their error. Seriously?
