29 Months Toddler

A man comes home after an assignment of 3-years and he finds, there is an additional member of the family, a 29 months toddler. Furious he demands an explanation:
He says, how could you have done this to me! Did you cheat on me with one of my friends, was it Josh, was it Nathan, or was it John?
His wife with a daring look says, your friends! Your friends! Don’t you think I have my own friends too?
