First, while carrying a photo of your partner in your wallet may seem like a romantic gesture, it's not mandatory. Each person has their own individual approach to relationships, and what may seem cute and meaningful to one person may seem superfluous and inappropriate to another.

Secondly, if you decide to carry a photo of your partner in your wallet, it is important to remember that this does not guarantee a strong and long-term relationship. A photo can be a symbolic gesture of love and affection, but it is not the end goal of a relationship.

Third, carrying a photo of your partner in your wallet can be risky. If you lose your wallet or it gets stolen, your partner's photo could end up in the wrong hands, which can be embarrassing for you and your partner. In addition, if you use public transportation or leave your wallet in plain sight, someone may see a photo of your partner and start asking questions that may be unpleasant or uncomfortable.

Fourth, carrying a photo of your partner in your wallet may be more important to some people than others. For example, if you're in a long distance relationship, wearing a photo of your partner can be a symbolic way to feel connected to them. In other cases, the photo may simply be an extra item in the wallet that doesn't really matter.

Thus, whether it is necessary to carry a photo of a partner in a wallet is a personal decision for each person. Some people may find it romantic and cute, while others may find it an extra item.
