Raksha Bandhan is a festival celebrated throughout India on a full moon day when traditionally a sister ties a Rakhi on her brother's wrist. According to Wikipedia:

The festival celebrates the love and duty between brothers and sisters. It is also popularly used to celebrate any brother-sister relationship between men and women who may or may not be biologically related.

Pappu Mishra, Somnath Sardar and David took Sunil to Lula Bari in the afternoon where the girls had all made threads for the boys in shuktara.

Sunil was the centre of attention and each girl put a Rakhi on his wrist as well as on Pappu, Somnath and David.

Because this is shuktara where equality rules Somnath and Pappu also tied threads for each of the girls!
