meme template is two buff men beating a rectangle with the following quadrants:
- rectangle labeled me saying: I just learnt object pronouns o/a, você, nos, os/as. portuguese isn't that difficult
- red buffed man labeled -lo/-la, -los/-las with infinitives laughing
- purple buffed man labeled lhe, lhes with verbs ending in a joining red and laughing hysterically
- both beating the rectangle while laughing, with rectangle crying.
Do not worry too much. At least in Brazil, almost no one uses mesóclise on casual conversation, and it can come across as pedantic.
