sample note:
Dear Smelly
For a clever bloke I thought you would have learnt the advantages of soap and water, and the use of deodourant.
Your BO is quite offensive and could quite easily be combatted by the following:-
1. Shower daily (using shower gel, soap, shampoo, carbolic or wash powder)
2. Use deodourant or anti-perspirant (available from all good supermarkets or poundland)
3. Change and Wash clothes on a regular basis (ie several times per week, daily changing of underwear is essential)
These 3 simple steps could even enhance your non-existant love life too.
Yours etc etc
