When you talk to them
kiss them good night
sit them around you when you watch your shows
gain the nickname tama mama [or dada for the men
]
talk tamas with your family and show off that cute character you got
their beeps are sometimes more effective than your alarm clock and could probably wake you from a coma
hold contests with your tamas, the ones that win get a special spot on your person when you go on trips [so they can see the world the rest stay in your pocket]
you keep them in your hoodie pocket when it is cold out so they are warm
name them after characters from your favorite shows or characters you have created
save up for tamagotchis all the time and get them in the order of your most wanted, going into in depth research, to decide which ones they will be [getting them all eventually of course]
the most effective way to get you to talk is by taking your tamagotchi away from you
if you take a nap you set your tamagotchis next to your pillow in case they beep for you
in case you don't notice... I am guilty of all... I am a sad excuse for an adult v_v
