some twins might tell you to actually hope that you are not twins at all.

What do you mean by this ? I'm confused.

Almost an inside joke but probably with some truth in it. Many twins are grateful to be in this journey in spite of hurdles. Others on the other hand have voiced their disappointment and frustration and expressed their desire to severe the connection. So to people asking if they have found their twin some here telle them to beware what they wish for, if they are expecting only butterflies and rainbows they probably don't know the journey may be at times... challenging.

but to be called out like that seems hurtful.

You will do just fine. I'd say don't even dwell too much over such trifles. your commitment to make it work will definitely yield results.
