[manyofa]

Kwa sobabu mbaya?

[AGreatUserName]

Kwa sababu mti ulikuwa mzuri sana na watoto walipenda kucheza juu yake. ;-)

kwa sababu = because (for reason)
kwa nini = why (for what)
kwa sababu gani = why (for which reason)

[juryrigging]

Mti umekatwa kwa sabubu watoto walipenda kucheza juu yake. Miti si safi!
