Saying ‘I love you so much’ or writing deep personal feelings when you’ve only met twice creates instant social awkwardness.

✖ 2. Joking About Their Age

Teasing someone about ‘getting old’ or wrinkles is fine for close friends, but comes across as rude to acquaintances.

A lengthy paragraph forces them to write an equally lengthy reply. Keep it to one or two friendly sentences.

✖ 4. Using Inappropriate Slang

In corporate or professional environments, avoid informal slang that compromises professional respect.
