I am the eldest of my siblings and my entire life whenever my age or birthday is brought up it is always in the context of people being shocked at how old I am. I have always found it quite hurtful and frustrating as I always have been made to act/be older than I actually am.
I remember being told at 4 I was too old to cry because I didn't want to go to nursery, at 8 I was too old to play with toys and so it goes on. Meanwhile my younger siblings have been able to embrace the age they are at.
I'm now in my mid 20s and I have a birthday coming up in December and the conversations have started - "I can't believe you're going to be X years old, wow you're getting old!" and then making comparisons "at that age I was married, had two children and owned a house".
I hate it and think it's so rude to tell someone that they are getting old. I never enjoy my birthday as I get these kinds of comments all the time from family and it just makes me feel really down.
Also as a disclaimer I know I'm not old, I am grateful for every birthday and every year of life I have. It's just the insuinations that I am so old, every single birthday brings me down. I remember at 10 crying because my family made such a fuss that I was double digits and was now SO OLD and grown up when I was still a child.
