I have the exact same name as another girl in my school, surname and all, and we're both in the same year. (I've even heard there are about three others with our exact same name but in other years) Because of this our report cards always turn out messed up, and now that I'm getting to the point where how my report card looks is important, I'm thinking of getting a nickname to differentiate me from the other girl.
I like the sound of Tessa, but am a little afraid about choosing a name that will be hard to implement. Since it's an international school in Southeast Asia, the teachers and staff (who will be the only ones who practically need to know/say/spell it) will have very different tongues.
Would there be any problem reading or spelling Tessa? Do people find it difficult to pronounce? Are there any other technical problems with the name you can think of?
Of course, I'm also worried about any negative connotations or jokes that could be made from the name (that one not so much, but it might get annoying), so feel free to add those or tell me if you know anyone called Tessa and how it is for them in real life!
