7. 5 Awkward Mistakes to Avoid
Saying ‘I love you so much’ or writing deep personal feelings when you’ve only met twice creates instant social awkwardness.
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.
In corporate or professional environments, avoid informal slang that compromises professional respect.
