A constant guest is never welcome

विना कार्येण ये मूढाः
गच्छन्ति परमन्दिरम् ।
अवश्यं लघुतां यान्ति
कृष्णपक्षे यथा शशी ॥

Those who visit others (frequently) without any reason, definitely have their dignity and status lowered gradually, very similar to how the moon loses its luminance from its full phase to new phase.

A constant guest is never welcome.
Familiarity breeds contempt.
