Bring her Lunch at work
No need to feel alarmed, you do not necessarily have to cook the lunch. You can just stop by her favorite restaurant and buy her favorite food or get something she has been craving for a while. It all will take very little time to execute and deliver. You can decide to also move you break time so that you can take you lunch break with her. It may be a small surprise, but it would make a difference in her day. She will surely love the opportunity to post a picture of such a romantic deed by her husband on Instagram or upload the story on Snapchat.
Give her public praise
Nigerian women generally like to be acclaimed and appreciated publicly. Just as sending lunch to her workplace will build her self-esteem and help her see you in a softer light. Praising her in public, like getting a radio station to dedicate a song to her or posting a love letter on her Facebook wall will do the same, especially when she hears others commending your actions or repeating your words back to her.
