You truly are a best friend like no other. I mean, who else would still want to be my friend after knowing all of my crazy quirks! Perhaps you're the crazy one after all!
You are my best friend and because of that, I feel it’s my responsibility to remind you not to blow out your candles too hard today as you wouldn’t want your false teeth to come out!
Having a smart, funny, and wonderful person as a best friend must be something truly special and a great gift in itself. You really are quite lucky, my man!
I’m wishing you all the best on your birthday today, pal!
You should consider yourself very honored and particularly lucky that you are one of the few people whose birthday I can remember by heart! You must be somewhat important to me, I guess!
I thought about trying and having a go at baking your birthday cake myself this year, but I quickly changed my mind because it seemed like a lot of effort!
