That’s funny. Some people really don’t notice things though. I have a friend with twins named [name]Alice[/name] and [name]Elsa[/name], who says they were about six months old when she realized how similar sounding they were and kinda hard to say together. I have another friend who never noticed her daughter’s full name until she was about a year old and her husband was joking with the baby – turns out he’d always noticed. Her name is [name]Carissa[/name] [name]Payton[/name], and dad likes to say “anyone want to go carrisapating tonight?” (Okay, it sounds funnier and cuter out loud.)
I hate siblings with extremely similar names though. I have friends with kids named [name]Andrew[/name] & [name]Andrea[/name], and another set named [name]Brooke[/name], [name]Brock[/name], and [name]Brie[/name].
I think it’s silly to worry about such things. They’ll only be “paired” as a set of names for a handful of years while they’re small. They are individuals, and if those were the two names their parents loved, who cares.
I bet it wouldn’t occur to the vast majority of normal people, especially if the parents don’t just refer to them as “sam ‘n’ ella” all the time.
